This piece originated in a time when  the composer had the impression, that at the moment the giants of jazz  die off from the world. It keeps to the traditional A-B-A form of the  jazz, however, the A and B parts are built up complex: After a 2-bar  introduction a bluesy theme follows in C major key, then a short, fully  notated bridge to a B minor part. After both parts are repeated there is  a short improvisation segment about the C major key part, followed by  that (this time differently notated) bridge which leads up into the main  improsisation part (B part) which can be freely formed. Then the A part  (bluesy C major part - bridge - B minor part) comes again and leads to a  final Coda.
