Record stores have been clearing space to stock what they expect to be this summer's sell out single, which started life as an Internet cult.
Everybody's Free (To Wear Sunscreen) by movie director Baz Luhrmann, which was released yesterday, has already clocked up advance orders in the UK of 400,000 plus.
"From the amount we have shipped we are pretty definitely expecting a No1 slot," a spokesperson for EMI Records said. "It has really captured the public's imagination."
The song's lyrics, however, started life as a tongue in cheek graduation address by Chicago Tribune columnist Mary Schmick.
The lyrics were posted on the Internet with a hoaxer claiming they were written by best selling novelist Kurt Vonnegut.
Luhrmann decided to take the lyrics and lay them over a track he included in his box office hit movie Romeo and Juliet. It initially had little response, until US radio stations decided to champion the song.
Luhrmann, director of Strictly Ballroom and Romeo and Juliet mixes the lyrics with an ambient backing track.
