As one can surmise from the large cast, this film is from the days when XXX played in theaters, and it wasn't unheard of to spend a couple of hundred thousand on the production, hiring a huge cast and even writing musical numbers for them to perform.

Yep, Blonde Ambition is a musical, starring Suzy Mandel (the cute, flossy blonde Brit) and Dory Devon (a slightly older redhead) as waitresses/songbirds in a cheesy country bar who get "discovered" by a couple of roues and taken to New York to perform in a play about the Old South directed by Jamie Gillis. There's also a subplot about a missing jewel held by Mandel, which leads to plot (and a few sexual) complications.

On the in/out front, several of the scenes are decent if not compelling, with Devon more of a turn-on than Mandel, but the multi-couple on-stage orgy falls flat, and rhe scene in the room with the ice rink is more production than heat. All in all, an interesting historical document that'll raise more eyebrows than cocks.
