I have a Rolling Stones song "Under Assistant West Coast promotion Man" in wave form, where after the intro, Mick Jagger's vocal drifts.  Is there anyway I can correct this using Cakewalk?  All suggestions are welcomed.  Ed

It all depends, is it in multi track format ?
Melodyne can do wonders but on stereo mixed tracks it can become tedious but possible.
 
Sonar comes with Melodyne but to do work with stereo mixed tracks you need Melodyne's best version.
You would get more precise answers with a little more detail. For example Cakewalk has many products. Which version are you referring to ? 

Chuckebaby:
  Thank you for your quick reply.  I have Sonar Artist and not the advanced version.  Are there any free plugins for Melodyne that would help.  Just how difficult would it be to correct the problem?  Thanks.  Ed

Is it a stereo mix or a multi track your have ?

Hi Chuck:
  It is actually a mono mix enhanced to stereo, using delays and with a short verse added by using analog in a studio.  Is melodyne included in Sonar Artist?  If so, where do I find it?  Thanks.  Ed

I don't think it is and certainly not the more advanced version that MIGHT help with this issue.

I'm wondering why you want to (apparently) retune an original Stones recording. It sounds unlikely that Mick would drift inexcusably much.

There is only a Melodyne Demo (essential) included in Artist. 
That's not the high end version and certainly not something you could use to pull this off.
TBH, im not even sure you could do it in Melodyne's best version (Studio). But it might be.
 

Chuck:
  To answer your question.  What we are attempting to do is create a mono to stereo conversion.  There are many of them on You tube and they sound really good.  I have done many and enever encounetered a drifting vocal before.  Ed

I still don't understand the problem. Couldn't/Shouldn't you do the stereo version of the exact original? Why would you want to change it?
Is it drifting in time or pitch?

I hear ya Kalle. I thought the same thing at first but I believe that song was recorded in 1965 (in mono).
Most bands from this era (Beetles early albums) were recorded in mono.
