Mike H, Uncle Dave,
Thank you guys, for your answers! I really like this forum comunity!
It's a real performance, and yes it's live (too good for an arranger, humm?). I took the audio clip from a tape recording I did while living in Paris, some years ago (94/95). I met Steve Browman - the pianist of the band - during the exams for a jazz school, which I didn't intend to enroll, because I was lacking of time. But this gave me the opportunity to ask him for particular lessons for some months. I don't remember the names of the other members in his band. If you are interested in further information, I found this on the Web:

Thanks again.
