Thousands of patrons—mostly youths in informal attire—waited overnight Wednesday at Madison Square Garden and at more than 100 Ticketron outlets for tickets to two benefit shows featuring two of the four Beatles, George Harrison and Ringo Starr, and the Indian sitar player Ravi Shankar.

The crowds came early and in abundance, demonstrating that the Beatles—or whatever is left of them—can still draw the fans.

In about 10 hours, 36,000 tickets were sold yesterday for performances scheduled to be held at the Garden on Aug. 1 at 2:30 P.M. and 8 P.M., ac cording to Allen Klein, the American manager of the Bea ties. Originally, only one evening performance was to have been given, but the faithful were so numerous that a matinee was arranged.

The Garden's box offices had been scheduled to open at 10 A.M. yesterday, but after the throng had swelled to more than 5,000 Garden officials decided to put the tickets on sale Wednesday midnight. By 8:44 A.M. yesterday all available reservations had been purchased.

The benefit performances are being presented by Apple Corps, Ltd., and Mr. Klein's company, Abkco Industries, Inc., which manages the affairs of the Beatles. Apple is the name of the Beatle‐owned recording, film, retail and electronic ventures.

Proceeds from the shows will go for the relief of the home less children and the millions of refugees who have fled East Pakistan to India. The relief will be administered through the United Nations Children's Fund. Ticket prices range from $4.50 to $10.

Also donating their services for the benefit concerts are Eric Klapton, lead guitarist, Leon Russell, pianist; Klaus Voor man, base player; Billy Preston, keyboard; Jim Keltner, drummer; Jim Horn, bass; Badfinger, rhythm guitarist and percussionist, and Claudia Lennear, singer.
