The 1st couple of bass parts I learnt in 1974: Black Knight by Deep Purple and Paranoid by Black Sabbath.
Many of Bourke Shelley's lines from Budgie albums up to & including Never Turn You Back O A Friend, (Bread Fan, his version of baby Please Don't Go, Parents, etc etc) .
I wasn't any sort of Purple fan but that's what I needed to learn for the band that had been the reason I bought the bass & it ended up being fun to play.
As you may probably guess, I strated musical life with a preference for hard rock & real metal.
Oh, that band didn't end up doing BK - the lead guitarist wasn't up to it - we played pop rock instead.
