Two of the four Beatles, the rock group that came out of Liverpool to make musical history in the nine teen‐sixties, were reunited on stage for the first time in more than four years yesterday. Over 40,000 people acclaimed them at two sold out concerts at Madison Square Garden for the benefit of East Pakistani refugees.

Performing some of the hit songs they had never played before a live audience, George Harrison and Ringo Starr thrilled more than 20, 000 cheering, well‐behaved fans at the afternoon con cert when they brought out an unannounced guest: Bob Dylan.

Those who had hoped for an appearance by a third Beatle, John Lennon, were disappointed. But most of the concertgoers seemed more than satisfied by the 2‐hour 15‐minute show, which featured some of the most famous musicians on the pop music scene.

“I'm shaking like a leaf; it's the thrill of a lifetime,” said a 17‐year‐old girl in the uppermost reaches of the Garden balcony who identified herself only as Debby of James Madison High School in Brooklyn.

Like an unknown number of others at the afternoon show, Debby was a gate crasher. She and two of her friends had paid $18 each to an unidentified official who sneaked them past the ticket takers.

“I've waited 8 years for this,” she said, adding that she had been “too young” to see the Beatles when they last appeared in August, 1966, at Shea Stadium.

The performers, all of whom donated their services, hoped to raise at least $250,000 from the concerts for the refugees. Mr. Harrison and Allen Klein, manager of the Beatles, had organized the concert at the suggestion of Ravi Shankar, the sitar player who comes from that area, who opened the shows with a set of Indian music.

Youngsters, some of whom had waited on line overnight at the Garden nine days be fore in order to buy tickets, showed up in droves early yesterday for the shows. Dressed for the most part in dungarees, and T‐shirts, they seemed a few years older than the screeching Beatles fans of old who had often drowned out the group when it played.

Although the overflow crowd cheered wildly when Mr. Harrison appeared to introduce Mr. Shankar at the show's opening, it was quiet and almost reverent during the musical numbers them selves.

Deputy Inspector Irving Roth, who was in charge of a 50‐man police detail, said after the evening concert that there had been three arrests during the day—two for robbery and one for criminal mischief. He said that some windows inside the Garden had been smashed prior to the evening program by would‐be gate‐crashers, who used wooden barricades as battering rams. However, Inspector Roth said that “All in all, considering that we had close to 50,000 people around here, it wasn't bad.”

The 8 P.M. concert was virtually a duplicate of the earlier one, with Mr. Dylan again appearing with the two Beatles.

When Mr. Harrison, Mr. Starr and the band took the stage at 3:37 P.M., the crowd jumped to its feet with a roaring, stomping ovation.

Mr. Harrison, slender, bearded and dressed in a luminous white suit, then led the band right into “Wah Wah” a number from his three‐record solo album that has sold a reported total of 3 million copies.

The band, which included such stars as Leon Russell on piano and Eric Clapton on guitar, next did “Something,” a Beatles number written by Mr. Harrison, which had been recorded on the album “Ab bey Road” but never done in live concert.

As their fans shouted and clapped its approval, Mr. Starr, in a black suit and beard, took the microphone beside his bank of drums for “It Don't Come Easy,” a hit he recorded after the Beatles broke up in 1970.

Garden security guards were kept busy keeping a swarm of amateur photographers away from the area directly in front of the elevated stage at the east end of the hall. Mr. Harrison asked the crowd between numbers to give the band a hand because “some people even canceled a few gigs to make it,” and the audience responded warmly.

Then, at 4:24 P.M., after Leon Russell had led the group through a pounding version of the Rolling Stones' hit “Jumping Jack Flash,” and Mr. Harrison had done an acoustic‐guitar rendition of the Beatles' “Here Comes the Sun,” a slight, curly headed young man wearing a dungaree jacket wandered out to join Mr. Harrison and Mr. Russell at the front of the stage.

“I'd like you to meet Bob Dylan,” Mr. Harrison said with a grin, as the audience went wild.

Mr. Dylan had not appeared in concert since his date on the Isle of Wight two years ago and he had never performed live with any of the Beatles. The audience buzzed about the historic significance of the moment, but Sal Prevete, a Garden security guard, was mystified.

“Who is that guy? he asked a reporter. “Is he one of the original Beatles or some thing?”

With Mr. Harrison and Mr. Russell as his back‐up guitars and later with Mr. Starr providing some tambourine rhythm, Mr. Dylan sang and played some of his most famous songs, including “A Hard Rain Is Gonna Fall,” “Blowing in the Wind” and “Just Like a Woman,” during a 23‐minute set.

Then, he wandered off with a little wave at the crowd, the full band returned, and the group did several of Mr. Harrison's big solo hits, finishing with his plea for East Pakistan, “Bengla Desh.”

As the crowd struggled out into the rain, there were murmurs of “fantastic,” “wonderful,” and “oh wow.”
