I think my most amusing moments were our family Christmas parties, when I was very young and when the whole family joined together as a small band, then swapping music to play unfamiliar parts. The results were often less than musical but very funny.
I come from several generations of a Salvation Army family, and was always surrounded by brass musicians.
My father played bass trombone, my grandfather eb bass and my great grandfather played cornet and a concertina. My two brothers play trombone and cornet and our father's two brothers were also cornet and trombone players.
