Here’s the first clue in the diagnosis.
I don’t know the Latin name for this delightful malady, but the lay population calls it this:
You might also know recorded versions by the Wolverine Orchestra, Fletcher Henderson, Eddie Condon, Joe Sullivan, Sidney Bechet, Humphrey Lyttelton, Doc Evans, Panama Francis, Mutt Carey, Johnny Wiggs, Kid Ory, Lu Watters, Turk Murphy, Miff Mole, Willie “the Lion” Smith, Graeme Bell, Jack Teagarden, Red Nichols, Jimmy McPartland, Ken Colyer, Chris Barber, Albert Nicholas, Buck Clayton, Earl Hines, Red Allen, Art Hodes, Dave McKenna, Kevin Dorn, Dick Wellstood, Alex Welsh, Wild Bill Davison, Kenny Davern, or other luminaries. And those recordings are in the last hundred years or so.
As I write this, some band or solo pianist is getting FIDGETY.
And I can now present to you a previously unseen performance from 2017, by the EarRegulars at The Ear Inn on a Sunday night. These luminaries are Danny Tobias, cornet; Scott Robinson, baritone saxophone, taragoto; James Chirillo, guitar; Frank Tate, string bass. Watch them go!
Thank goodness for these players; thank goodness for The Ear Inn.
May your happiness increase!
