I don't know - I kind of like the juxtaposition of eras on "...Four Leaf Clover" ! The singer is Billy Murray, whose recording career went back to the turn of the 20th Century, and right after the vocal the band comes charging in like a volcano, with slapped bass and Bix-led brass section, and then one of my all-time favorite Bix breaks - in which everything stops so Bix can add his exclamation point to the whole thing. The old and new, right there to hear. (And let's not forget Joe Venuti). To me, that's pretty cool! Great coda, too.
(And I'll admit it - I'm a Billy Murray fan since I was a kid, and still find him great fun to listen to).
