The best ever wasn't around too long - Dire Straits.
My favorite - Steely Dan.
Best concert ever - Grateful Dead at Cow Palace (1972?).
Worst concert ever - Grateful Dead at Fresno Sports Arena. (1974).

What group really is the best?
Keep in mind, we "seasoned" members grew up during the best
musical period in history, all genres.

Ride Safe, Dennis Triumph, it's how I live and what I ride.
