Nine O'Clock Jump

As I shot grasshoppers jumping about this evening at nine in the special bit of our meadow that I have persuaded MrQ not to mow, the title above popped into my head. I have absorbed much of the stuff that MrQ plays through osmosis, I have never gone to his gigs. I was suffering from false memory syndrome. It's not nine o'clock but One O'clock Jump. :) A big band Count Basie standard which MrQ used to play on the Town Hall dance circuit. https://www.youtube.com/watch?v=08jyOwx96Ig
