Paul Mauriat's Sweet Charity (1969)

Soon after the release of Bob Fosse's film Sweet Charity (1969) (which adapted Fellini's Nights of Cabiria (1957), via the stage-show that Fosse also directed and choreographed), Paul Mauriat rearranged and reorchestrated part of Cy Coleman's Overture for the film into this magnificent pop-classical/lounge band confection. This piece of music was a single from Mauriat's 1969 album, Un Jour, Un Enfant (front: http://tinyurl.com/b9r54e7 and back: http://tinyurl.com/atgr7jy), and was used as background music, e.g., for events montages, Olympics coverage, etc. throughout the 1970s.

Fosse's film starred the great Shirley MacLaine as Charity Valentine. While Sweet Charity (1969) is arguably a bit of a dud overall, MacLaine herself is dynamite, as is much of the music and dancing. Many of the stills I've used come from a very warm appreciation of the film due to Ken Anderson here: http://tinyurl.com/98d7qy9 .
If you want to see what a completely successful, ultra-dramatic version of the underlying story looks like, I strongly recommend watching Nights of Cabiria (trailer here:    • Fellini trailer Nights of Cabiria 1957  ). MacLaine is so versatile that she would have been able to star in a straight remake of Nights of Cabiria as well as Fosse's musical!
