Ah I see. So at the moment of his singing the cocaine song, he did have some to offer around. He was merely recounting the time when Mr Lehman hadn't any, but since then he has found an alternative supply, which he's generously using to give to a lady.

As we're dealing (sorry about the pun) with my pedantry, what about the words to 'On The Road Again'? He went to his house and the door was locked, but he looked in and saw a n***** in his bed. So he shot through the window and hit the unfortunate unofficial lodger 'in the leg', then adds he'd never seen a little n***** run so fast. I would have thought he really meant to sing shot him 'in the ass' which would rhyme in a way with 'fast'. Perhaps 'ass' wasn't allowed to be sung in those days?
Once I've got these things sorted out, I promise you'll hear no more about it.
