It was at the Canadian Songwriters' Hall of Fame induction gala at Massey Hall on Sept 28! If you haven't seen other videos on RU-vid yet, do a search for them. ShakyShorty has all of the tribute covers done for Blue Rodeo + Jim and Greg on stage for "Lost Together." I also have "Til" by Tim Hicks and Tenille Towns (still need to upload) but there are a few more that I didn't get.
