If you want motown there are several options around town:
the InCrowd do a weekly (was at Czehoski, not sure now)
SplatterMonkey does things in random venues downtown west
and Parkdale Funk is also involved in a number of nights, including the recent SuperSoulFunkRevue with the Main Thing (that was too much fun!).
Info on all of these available on that fb place..
There's also a Motown Party at 751 Queen West. It's been going on for over a year. In fact, most of these newer Motown nights are riding the coat tails of the 751 party's success.
