Here's how it works in the reissue licensing world.
You call up your label rep. You have a list of titles you want to reissue. You read them to the rep and he\she punches them into the label database and says ' no, that one isn't available' or ' yup, you can have that one and this is the cost\ terms.' If you punch up ' Live Wire\ Blues Power ' it may very well come up as unavailable, due to the label having identified it as a candidate for reissue themselves. It may come up as available, but no master tapes - so you have to decide if you want to reissue it from digital, and take the flack for that.
if you call up Universal with a list of Impulse or Verve titles, you will get mostly 'no' as you go through your list. You might get lucky and hit a few that are available, and even say there is tape available. Great - you agree to license it, and find out when the tape is delivered to the mastering studio that it is a copy of the third generation Yugoslavian cutting master - and you cancel the project and eat the costs incurred so far.
That is how you end up with Money Talks.
