After I  started playing bass, I don't play much guitar anymore...
It's so much more fun to play bass, I think!    
+ It's so much easier to sing and jump and headbang and all that other stuff when you play bass!
Yeah, Cliff Burton was the great one... 
But my favorite bass-players right now is Geddy Lee (Rush) and John Myung (Dream Theater) 
Not because of their attitude, but because of their playing...

I'm looking forward to the lesson, oldies.
I hope you can teach me a lot of new stuff!
