Imagine a rather flamboyant pirate playing the trombone, with plenty of yo ho ho and more than likely several barrels of rum.
I met a trombonist during a production of the show Anything Goes and he had to play the trombone in a drunken manner in one of the songs, lots of sliding between the notes. He said it was a technique he had had to employ on a few occasions.
Nothing personal, NB, but when I saw the title of this thread I rubbed my hands in anticipation of some juicy gossip. Then I found out it was about a bass trombonist, which I suppose is the next best thing. Welcome anyway!
