It's interesting to see stuff about discovering Gordon Lightfoot late - sort of like I did Mark Knopfler. I keep thinking it's like "discovering" for yourself a well-known and prolific author. It's like you have a treasure chest full of books (in this case, songs) to encounter for the first time.
I've loved Lightfoot for years, but I have to say, when I play his albums (I have a bunch on vinyl), I always feel like skipping this song or that. Not so with MK. I love all his stuff. I only skip "If This Is Goodbye" or "Far from the Clyde" if I'm listening somewhere where I can't cry (seriously).
Here's a thing: Give a listen to Lightfoot's "Canadian Railroad Trilogy" and see if it doesn't remind you of "Telegraph Road." Oh, and also try "Ghosts of Cape Horn" ... just because it's so cool. Sailing ships seem to inspire both these composers in a wonderful way.
