Guest: Does the question mark in the thread title imply that you aren't sure that Andy Irvine sang this song? If it wasn't him, do you have any other guesses who it might be?

Andy Irvine's website doesn't mention any song called GENERATIONS.

AMG - All Music Guide lists about 40 recordings of something called GENERATIONS, but Andy Irvine isn't there. You might look over the list and see if any other names ring a bell.

It might help to know the exact name of the performer and album.
