New York, Aug. 24 - Last night, The Beatles came to Shea Stadium and 55,000 fans came to their feet en masse to welcome the world's top rock 'n roll group in what may be their last-ever appearance anywhere as a group. The millions of fans unable to attend this historic performance can now share with the fans who were there, the sounds, the build-up of excitement, the surging expectation and the enthusiasm that greets the Beatles as they come up on stage. Hear fans as they board subway cars at Broadway and 42nd, headed for the Stadium. As the train starts up, girls talk about John Lennon and Jesus Christ. Then you're at the stadium, Barkers are selling binoculars, ""Get up tight with The Beatles tonight."" Two girls tell why ""they make me so happy."" You begin to feel the excitement building up. Preliminary groups come on, but are all drowned out by the constant groundswell of sound pouring from the stands. 'The M.C. leads the whole stadium in singing, ""We love you Beatles."" Its a big sound. The Beatles come on and there is a stupendous roar from the crowd. You hear the individual close up comments from the girls as they react to their heroes. Boys describe how kids are leaping the fence, trying to get at The Beatles. Several hundred of N.Y.'s finest cops take up position in the infield and brace for the possible onslaught. 9 Tracks Total
