The last songlist on www.lightfoot.ca showing a concert performance of "Canadian Railroad Trilogy" was 28Apr2018 in Beverley Hills, California. It would be sad if that iconic Lightfoot song has been permanently shelved.
I have read that there are some songs that Gordon can no longer sing due to his stomach issues, BUT, then he has said, he can sing songs he never really did before in concert, is what I read somewhere. Mike
He can't do the long winded phrases and get tot he notes he wants and I imagine for some tunes he doesn't want to change it up to suit his voice..
Most songs that are 'new' haven't been done in along time and he changes those few up every couple of years. lightfoot.ca has tour info with setlist for prior years..
