I'm going to say it again. "Nothings worse than hearing a great live arranger keyboard performance and then having it completely RUINED by a 'canned sounding' ending/intro."

One of the things I like to do for an intro is to vamp on a chord progression (2 to 4 chords) and then improvise an intro live. For endings, I typically delete the melodic parts of an 'ending style' and improvise the melodic part live as well. By doing this, the entire song sounds integrated because YOU are playing thru the 'entire' tune. - Scott
