I hope we're talking about the same Mosaic set. I mean "Classic Columbia Condon Mob Sessions".(MD8-206)
I count 4 sessions for PeeWee and 4 for Peanuts. Counting alternate takes I make it 21 cuts for PeeWee and 14 for Peanuts. As for being available elsewhere there are some 29 out of print lp's this Mosaic was culled from. Go figure what your chances are.
There is another condon Mosaic--"The Complete CBS recordings of Eddie Condon and his Allstars"
MQ7-152 which is, except for the last record, terrific. If you haven't heard their version of "Old Mis" you have missed the best hunk of that brand of Chicago style jeaa. IMHO
