Watch the Daylight online guitar lesson by Jeff McErlain from Essentials: Chord Tone Soloing
I love Creedence Clearwater Revival, and I think John Fogerty is one of the best rock song writers and singers. He clearly has roots in the soul and blues, as we can hear on the song "As Long as I Can See the Light". This one is a full-on gospel chord progression that's fairly common. It's a great song to learn how to navigate the changes as you'll most likely come across them again, and they're fun to play over.
The song is a variation on a basic I-VI-IV-V progression in B. So that would be Bmaj-G#min-Emaj-F#maj. As always, learn the progression in as many locations on the neck as you can. Think small three string triads on the D, G, and B strings, as these are in the "magic zone" on the guitar.
