Vido Musso was a good player who played with, a.o., Goodman before Kenton. With Kenton, he got a LOT of profile. Certainly a fine player, but a "big dog" he was not, especially not considering who all the "big dogs" of that time were.
Still, if you have a chance to get that 78, go for it. Ideally, you kennel should make a home for good dogs of all sizes.
