Interesting, Gary, sort of a 'scaled down' version of something the Trans-Siberian Orchestra would do ...

Scott, I use the transpose technique quite a bit while changing variations, especially for instrumentals, or 'sing-a-long' songs like. "Down By The Riverside", and for songs like "Cab Driver", Bobby Darin's "Clementine" and "Mack the Knife" I think it's a MUST ... helps lift the song to a big ending ...
