Don Byas April 25, 1970
A recording of this exists at the Musice Center for the Netherlands: http://catalogus.mcn.nl/cgi-bin/koha/opac-detail.pl?biblionumber=303199
We received the track play times from that copy. In addition to the musical tracks, there are tracks of stage patter, chatter and an introduction of band members. Since this is neither spoken word nor musical, I will just list the tracklengths and where they occur below:
Before track #1: 00:00:34 of chatter
Between Tracks #2 & #3: 00:01:21 of chatter
Between tracks #4 & #5: 00:01:10 of chatter
Track #7: The archivist at Music Center notes that the last 00:14 of this track is a Byas solo, where he plays the ending theme of Dizzy Gillespie's tune "Bebop" as played originally by Charlie Parker.
Between Tracks #7 & #8: 00:00:29 of Band Member introduction
Hazavoet lists all these tracks as occurring during the same live concert at Zodiac in Amstelveen. The archivist who has the copy of the recording, however, indicates that the two sides of the album are of very different sound qualities and since the only band introduction is on the second side, he said he could not be certain that they occurred during the same session with the same personnel.
