SAN FRANCISCO (UPI)—The one and only Ringo Starr, mop topped drummer for the Beatles, stopped over briefly in San Francisco airport Friday while a goodly portion of the Bay Area teen-age female population screamed a welcome to him. Five of the 300 fans who wel comed him were rushed to the first aid station with undeter mined illnesses after nearly swooning with delight. Ringo, who has been in a Lon don hospital for treatment of tonsilitis and pharyngitis, tried to silence the girls by putting a finger to his lips. But the girls continued to scream “I saw him!” “I love him!” ‘We love you Beatles, yeah, yeah, yeah!”’ and other apropos comments. Starr stopped over in San Francisco on a flight from Lon don to Australia. He is sched uled to join the other three members of the long-haired singing group there for a tour.
