[Oric Muso]

I've got the tune written out for this nice Latin piece.
I'm struggling with the chords. It rattles along so briskly it's hard to hear.
Can anyone help out with the chords in either concert or for Bb tenor?

No one? Here's some rough chords which might be somewhere near to the right ones.
Starts off oscillating between two chords. F and Bb I think though I'm not 100% sure. Then something like....
||:F (?) | Bb |F C |Bb |F |Am7 Bb| Eb Dm Db Cm |(1st repeat) Bb |F7 C :||
(2nd repeat) DbM7 |Csus4 || Bbm7 Cm7|Bbm7 |Abm7 Bbm7| Abm7 |Am7 EbM7|Gm7 DbM7||DbM7 |Csus4 |F |Bb |Dm C | Bb ||

Some of the Bbs may be Gm7. Some of the notes seem to indicate a Dm rather than an F. I'm not sure about the bar with 4 chords. It doesn't look right on paper. Any help???
