I wasn't the only person in the world who mixed up names. One time in distant 1964, somewhere in the greater Los Angeles area ... when I was young and with a budding composer. We were sitting in the living room on the couch awaiting the always pretentious classical radio announcer on KPFK to finish droning on about the piece he was about to play.
It was to be a famous suite by Handel, but he flubbed the name, mixing Handel's "Music of the Royal Fireworks" with Handel's "Watermusic", announcing it would be "Handel's 'Waterworks'".
I don't remember which suite he played, I nearly peed from laughter.
