But yeah, I hate when they split a live set up like that. Glad you dug "Pep's" and yeah vol. 2 is just as good so you'll definitely wanna grab that but it's lame that you can't find it cheaper- think it's just been out of print for awhile unlike vol. 1, might've even been the case when I got my copy.
If you don't care too much about sound quality, you can just rip vol. 2 off YouTube. And speaking of live Lateef albums on YouTube, the set from Ronnie Scott's from a couple years later is also ridiculously good: https://www.youtube.com/playlist?list=OLAK5uy_koKNkfi1rRZuaVbcYEvVs3s8XDEAbjvR4
