Ron,
I believe alternates takes are worth having. They can be completely different at times than the master. However, there are various schools of thought on this. Looking at it a different way, I want every alternate take that's on the Bird Dial Savoy set. Where would we be without the famous alto break on Night in Tunisia?
In addition, the Vee Jay Mosaics were loaded with alternates takes and I'm glad I have them.
BTW, you can always program around them.
