I remember, one news years eve, my parents had a party and my elder brothers got me drunk by drinking capfuls of neat gin. 'Go on Mart', they'd say, 'this is rock star stuff' I think I was maybe 14 years old, maybe even 13. I'd have a capful (the cap that screwed onto the bottle) then I would disappear upstairs to my room and pick up my bass and play along with some Duran stuff. I remember being able to play 'my own way'. Because I was so relaxed (drunk) I learned to slap the part.
I learned all the parts from the Duran stuff. (and the Jam and the Police)
