Daveboy,
OK - this is for a full track - I just wanted a play-a-long for an Alto Sax student for two pieces that are in "E" for the original key which puts the poor soul in C#.
I wanted to bump the original up to "G", a minor third, not caring too much about the chipmunk vocals as long as he can play his part along with the vocal track, and I would like to keep something near the original tempo.
Initial results with Celemony Melodyne are relatively useable.
Logic's tools in the wave form editor may have more possibilities than I initially found - I managed a pitch change, but not without altering the tempo accordingly - more fiddling may be needed

Thanks for taking the time to give your advice.
