Ed,
So Howe McCormick played the trombone. Great discovery.
Sifting through the archives of musical history. I have been unable to verify Nelson Tisdel's musical instrument or preference, but I have discovered that Scott Tisdel is the principal cellist for the Milwaukee Symphony Orchestra.

Certainly the resemblance to Nelson is unquestioned.
Obviously musical talent and a propensity to stamp vintage cards must be located on the same gene. I will try to find out what Scott is stamping these days other than his foot in time with the music.
