Change O´Key Boogie! As the title suggests change of key live here, that is the soloist. There is some fine solo work a bit of an ensemble here and there, swinging all the way.
That´s plenty - the tune gives the album it´s title, is a well known standard or at least it was back in the day. This version features the sparkling trumpet of Doc Cheatham. Doc is up tempo and keeping this standard exciting from some of the more lackadaisical versions you can hear from time to time in other places. Fast and smokey.
