I started listening to this only to immediately realise that I know and love it well, great song. Cocaine was very popular around that time. If you like that sort of thing, there's a very good compilation of old blues songs about drugs called "Junkers, Jivers and Coke Fiends", on which "Cocaine Blues" is featured, though I have to say Charley Jordan's version of "Spoonful" stands out as the best inclusion for me.Heres one, apparently cocaine addiction was an issue in the 1920's aswell, listen to this one with an open mind really interesting lyrics: http://www.youtube.com/watch?v=p6tfNVbgwu4
