I just finished watching the Gordon Lightfoot documentary "If You Could Read My Mind" on Amazon Prime. Wow. I highly, highly recommend it for any Gordo fan.
Prime has a few good music docs. I'm watching one on the Police now. It's reinforcing pretty much every negative impression I've had of Sting. (Granted, it's Andy Summers' movie...)
Been a Lighthead since I was a kid. I think his Canadian Railroad Trilogy was my intro to the whole folk genre. He got played a lot on Canadian radio in the 60s & 70s…I could pick up all the Windsor stations from my Detroit area home.
