Since Gordon Lightfoot & I are "almost" the same range,except for that vibrato,I find a lot of his songs to be fairly easy on my vocal chords.
If You Could Read My Mind,
Sundown,
Carefree Highway,
Rainy Day People,
(if I could memorize the lyrics)--> "Wreck",
The Circle Is Small(I Can See It
In Your Eyes '78),
Baby Step Back,
Rainbow Trout,
Shadows,
Forgive Me Lord,
I'll Tag Along,
Cotton Jenny,
End Of All Time,
The Pony Man and quite a # of his 60s.
Too many to list really.
