I just had to mention this as I got played this by a Jazz tutor at Summerschool and I am now totally obsessed with it. So there is a 10 minute plus version on the Musiquarium compilation that has a solo from Dizzy Gillespie and extended improvising from Stevie. But the bass line has such amazing energy and groove - great little fills and a sound that is almost like synth but there's some great improvising towards the end! I just can't understand why I haven't come across this before - the tune sounds very familiar - but I'm sure I haven't heard a version this funky before, or I would have had to buy it!! So - why is it so "obscure" when other tracks get played a lot more IME..?
