There'd be far too many too list because I think it'd be just about everything.
(Most likely the songs I put on my old list of 150 Lightfoot favorites.)
To name five though,in no certain order ;
1. The intro to End Of All Time. Talk about setting the mood of the song.
2. Sundown,naturally.
3. The Wreck Of The Edmund Fitzgerald
4. Baby Step Back
5. The cool easy groove of Make Way For The Lady
Many more but those are quite fine.
