Not quite age 18, with Pursuit at the 1974 L.A. County Battle of the Bands, at the Hollywood Bowl (we tied for first in the combo division.) This was actually not my first time performing there - I marched with the L.A.P.D. Junior Band that played a few events there in 1971/2.
The flute player is Jeff Rona, who went on to prominence scoring for TV and movies. The piano player, Bill Turner, was one of those guys who could pick up any instrument and play it, well. Trumpet, guitar, flute, even drums. I'm still in touch with guys, although Bill is very sick right now. Jim Walker played bass, and was the clown of the group. He and I were both major Zappa and Bonzo Dog Band fans. It wasn't unusual at rehearsals to launch into bits from Billy the Mountain, or start playing Can Blue Men Sing The Whites. Unfortunately, he passed away at a very young age. His was probably the first death of a contemporary I'd even encountered.
The drums were my Ludwig Standard 5-pc in Blue Mist (I typically only used one of the rack toms.) What a terrific kit, and sadly, long gone.
