This was recorded at the Montreaux Jazz Festival in Switzerland in June 1969. Both the Eddie Harris Quartet, and the Les McCann Trio performed with great success at the Festival. Later in the week, Eddie and Les felt like playing together. Benny Bailey, the great American trumpet player, who was living in Europe, was also there; he was asked by Eddie and Les to join them; the rest is history.

1969 was also the most fantastic Summer of my life; when I went to lawn parties, I always brought plenty of Cold Duck Wine, and I inquired when I arrived, "What time is it?" always, the hearty response was "Its Cold Duck Time!".
Those were the days my friend, why did they have to end?
