Paul Desmond is mostly known for being the saxophonist in the Dave Brubeck Quartet for many years, and in particular for having written "Take Five" on the ever-popular Time Out. Here's a clip of Desmond leading a quartet at the Monterey Jazz Festival in 1975 playing Desmond's ballad "Emily":Incidentally, there are several versions of the Brubeck Quartet with Desmond playing "Take Five" up on YouTube. None of the performances really grab me, but if you need to hear it check out this version from 1961 on Ralph Gleason's Jazz Casual show.
