Please identify this song for me.!

When I was young I used to watch POGO.In the jukebox they play several songs repeatedly. One such song has caught my mind back then and now I suddenly felt nostalgic and I wanted to listen to it. But i do not remember the name of the song nor the artist. I will try to describe the song with the best accuracy I can. It features the artist with a guitar singing and huge loudspeakers at the other end. All ppl rush to the loudspeakers giving seldom attention to the singer. They all enjoy the song and only a girl notices him. Suddenly he starts floating in the air and keeps singing. Please identify it.!
