Nice ! Did the vice squad call in to confiscate the whistles?
Would that have been the Junior Cook/Louis Hayes Quintet gig back around 1976 where Cook fell out with the rest of the band (if my memory is right)? I know that Melody Maker had a story on this - slightly before my time at Scotts unfortunately.
The Woody Shaw group I saw was a few years later and had Mulgrew Miller on piano, Stafford James on bass and Tony Reedus on drums. Steve Turre on trombone, of course. Just before they recorded 'Lotus Flower' for Enja Records.
I wonder if it was the Woody Shaw/Louis Hayes Quintet with René McLean, Ronnie Mathews and Stafford James who recorded a Swiss Radio Days album in Lausanne in 1977? Mind you, it's surprising that I wouldn't remember Louis Hayes. If they didn't appear at Ronnie's, that settles it. It wasn't them!
