somewhere over the rainbow
Somewhere over the Rainbow the writers thought it was to long
An idiom is a phrase that makes no sense unless you know the definition. Could there be "somewhere over the rainbow?" Yes, you could have a place that was beyond or over a rainbow, so this is not an idiom. The song is talking about a place that Dorothy thinks is better than where she is now, that she thinks might be beyond the rainbow she sees.
On Steve Vai's website he said that he never did a version of somewhere over the rainbow... The song must of been uploaded on a file sharing site by someone playing in the style of vai.
