As always, your posts Dave Ram... great ones
I would say "Band on the Run", I think it's probably the best collection of songs that Wings ever included on one disc. "Venus and Mars" is true, it sounds far more interesting. The sound quality of that album is quite poor. Just listen to Medicine Jar or Rockshow. It sounds like it was recorded inside a bath... But, thinking about it, tracks like Jet or Mrs Vanderbirlt from BOTR also sound poorly. What's happening in the early 70's?
So my vote is for Band on the Run, best Paul album in my opinion probably after Ram and Tug of War.
