Randy Bachman is doing a two-hour show on CBC tonight in honour of John Lennon's birthday. Lots of archival music and great commentary.
If you go here:
It's on from 7-9 Eastern Daylight, but if you scroll down and click, "see what is playing on all live streams," you can pick the show up when it airs in Vancouver at 10 p.m. Eastern. It will probably be archived as well. I'll post the link when the archived podcast comes up.
