Right now I have no means to connect my computer to the HiFi. But it is on the list.
To make sure one would have to compare all existing issues of a track. Sometimes they are just different edits, sometimes they are alternates. Some of the tracks on compilations are leftovers from LP sessions, like the Teddy Edwards with Hampton Hawes, which was made at a Jimmy Witherspoon session. Many labels did so, but Richard Bock was the wildest.
