Nice, I really dig that tune. Now, I'm just waiting for some Louis Prima stuff to turn up from you! Come on, Jump, jive, and wail!!!
now your REALLY talking 30's music
My biggest factor is no fretless, no upright, so it will never sound authentic ---so all I can promise is that if I do it, it will be "note" correct ( or at least as long as I can HEAR the bassline ) clearly under all the other junk in there.
30's-40's music is so....so......so..... walking bass line-ish ( but at least the chord structuring is consistent )
