@IdRatherBeSkiing The Toronto song's opening riff sounds to me like a bastardization of the opening riff of Jesse's girl. High - low -middle. But when Toronto hits the verse it's even less bastardized - the guitar gets muted (just like Jesse's Girl) and the four first notes are the same. Just taking the concept that each riff has 4 notes, here's how it breaks down:
Jesse's = 44 22 33 (rest) 1 133 44.
Toronto = 44 22 33 (rest) 1 1 1 3 2 (then next time it's even closer) 44 22 33 (rest) 1 1 33.
Dock Of The Bay is a re-recording by Otis' sons. From the oh-so-reliable Wikipedia: "The Reddings was an American funk, soul and disco band, founded by Otis Redding's sons Dexter (bass and vocals) and Otis Redding III (guitar) together with Mark Lockett (drums, keys, and lead vocal)."
I don't play guitar and I have never heart the similarity. But maybe I am hearing the music not the tempo which might be more noticed by a guitar player.
