Career
He replaced Comrie Smith in 3"s a Crowd and played with the band from 1966 to 1967. Koblun began his music career as the bassist for the Squires, a teen band formed by Young in the early 60"s out of Earl Grey Junior High. After the band broke up, Koblun found work playing bass for various folk musicians.
However, he stayed for only a few days before deciding to return to Canada where he joined up with 3"s a Crowd.
In January 1967, a replacement was needed for Bruce Palmer, who was fighting possible deportation. Koblun only played with them for about a month before the band decided his personality was undesirable and his bass playing not as good as they anticipated.
During that time he did appear in one of the few film clips of the band, doing lip synchronization to "Sit Down, I Think I Love You" on the television show Where The Action Is. Koblun did not record with the band, but Young"s epic "Broken Arrow" is dedicated to Koblun in the sleeve notes of Buffalo Springfield Again.
Koblun appeared on the 3"s a Crowd album Christopher"s Movie Matinee.
He has worked with various musicians such as, Richie Furay, Stephen Stills, Dewey Martin, Donna Warner, David Wiffen, Trevor Veitch, Brent Titcomb, and Richard Patterson.
