David Zimmerman from Minnesota,
Managed Skogie (& the Flaming Pachucos) in the early 1970s. At that time his company was named Bernard Productions.

David secured Skogie's first recording contract and produced their first record (The Butler Did It) at Sound 80 Studios (where 'Blood On The Tracks' was completed). 

"David offered to get us an unrecorded Dylan song to record, which we, like idiots, turned down without even listening, because we wanted to record our own material!"-Moore

P.S. David's son Seth has a great band named: Tangletown. Check 'em out.
