The notation I have this week (which I was going to do last week but completely forgot about until it was late at night) is a little different from what I've done previously. Because most of the bass part for the Spencer Davis Group's "Gimme Some Lovin'" is just the same measure of G notes (with the last note in a different octave) over and over again, I didn't write out the notation in full. I have one line of that repeated measure; I skipped the second line (although I still have bar lines because I insert bar lines into a couple pages of blank notation at once and then use them for various projects later); and the third line is the only different part (for "And I'm so glad we made it..."), which transitions back to that repeated measure with a glissando. That same measure of G notes is repeated to the fade out at the end.

Because that measure with G notes is so prevalent, I think the song is in G major, although there are also Bb and Eb notes, so I'm not positive on the key. I should mention that I figured this out about four years ago, and I'm assuming that what I have is accurate.
