Hello, I'm a recovering guitarist! I've been playing bass for many years but am usually criticized for playing bass like a guitarist. This is probably true but I've really been getting into the bass in a big way and want to approach it with a lot more intensity. I've decided I need to learn from the masters. To get the ball rolling this weekend I worked out the bass lines for "Being for the Bennefit of Mr Kite" and "I Want You (She's So Heavy)" Beatles, and "I Want You Back", Jackson Five. What bass lines do you consider to be classics and must learn tunes?
