I also remember the laugh. But if my (very) ancient memory serves me correctly, I believe the laugh occurs at the end of UNSQUARE DANCE and not TAKE FIVE.
Dave Brubeck-Take Five
On the original LP of "Time Out", didn't Gene Wright laugh at the end of "Take Five" with a reference in the liner notes that it was relief at making it through the track? The laugh is gone from the CD re-issue. Anyone have the LP? Or a memory unaffected by the excesses(!) of the Sixties?
