Actually, here in the UK again, we had a comedy show called The Fast Show which had a section called "Jazz Club". Here's some clips - just so you understand why so many UK guys say the word "Niiiiiice!!" whenever the work "jazz" is mentioned: ( I love the Jamiroquai rip-off at the end "I don't need no melted chocolate on the seats of my Ferrari")
My "Jazz" consists of playing chromatically, 'till I find the note I was looking for. Seems to work O.K. And no one knows I didn't know where to find the note.
