The same Led Zeppelin that borrowed all those American blues and country riffs throughout their career?
If you educate yourself on American music from the 20s-50s you'll realize the true extent of the influence on the British music of the 60s and 70s. It's a lot more than Rocky Raccoon but if you're ignorant of country music you're not going to hear the guitar licks, drum patterns and vocal inflections that show up in many of the recordings by the Beatles.
There's no shortage of literature on these influences so how about we just leave any additional education on the matter to personal study, eh?
