I remember seeing them in Aurora in 1965 at an out door concert.
In 1965 I remember the teenagers in Denver belonging to three tribes: The Surfers, who had a Beach Boy look, not letting it bother them a bit that the nearest ocean was several hundred miles away and the Soches, who had a vaguely Beatles look, but with Army surplus jackets and corduroy pants...Downtown still had lots of Greasers with the whole "Wild One" "Brando is God" look.
