Dave Traynor has it right. He points to Randy Bachman's Saturday night show on CBC Radio One as "arguably the best music show in the land."
Bachman hosts Randy's Vinyl Tap, which uses his personal perspective as the lens through which he views a musical theme, event or time period. If you haven't tuned in, make a point of listening Saturday nights 7 to 9 p.m.
Of course, Bachman isn't best known as a professional radio host. He was the creative driving force behind Bachman Turner Overdrive, and (with Burton Cummings) The Guess Who.
