There are tutorials on most famous bass lines, but they’re not all of them are correct. I was trying to figure out how to play the end part in Saturday in the Park recently and went though 8 YouTube videos before I found one that was actually playing something close.I just found out yesterday (ok, I'm always a day late on new tech), trying to learn Good Times Bad Times, found a great tutorial on YouTube (in Brazilian?), he slows down the tempo to demonstrate, and also, there is a looper app you can add to YouTube.
