In Fletcher Henderson's band, the Hawk was known to take some choruses on clarinet, one of which was preserved for posterity on 1931's "Hot and Anxious" which can be heard here. We can all be glad he decided to focus on tenor sax shortly after this, but still, it's Coleman Hawkins taking a chorus on clarinet, and the solo (which begins at around the two minute mark) has quite a bit of Hawkish character!
