"Ooh la la"

Well, the lyrics... ooh la la... Pure sexual innuendo nonsense. :)

Chords for intro and the verse are
G F C G
G F C G

and the chorus (the "ooh la la" bit):
C G C D

So by those it's easy to say that this song is in G mixolydian. In the key of G there'd be no chord of F, you see. Mixolydian is like the seventh chord version of major scale (which is maj7 scale, so it has the F#, not F).

Hey what's with the solo, it's clear as a bell! Is it some Albert Lee solo or what? Sounds like it was played with a stratocaster. Maybe the mocha colored one on the "in session" DVD, who knows?

...so the solo is in G mixolydian too. Or, basically it's the G major pentatonic scale box #1, but the C note (i.e. fourth note of the G scale) is added. Typical slides and bends up to the major third (very common in country and blues).
