Got to agree about the soundtrack - it's terrific in its own way. The problem is that its so close to the real thing that most casual listeners (like my dearest wife and kids) can't tell the difference between the parody (a mighty wind)and the real thing (the albums Dad listens to when he'sworking in the basement).
My favorite things - and there are so many - The comment by somebody at the pre-show party at the dead promoter's palacial digs: "Who said you can't make money in folk music" (or something to that effect). . .
The quaver in the high tenor of the Folksmen, so like Glenn Yarborough and the Limeliters. . .
The recording quality of the Mitch & Mickey songs; they are really tender, even if totally corny. Reminiscent of Richard & Mimi Farina. . .
The relentless cheerfulness of the (New) Main Street Singers, so like the Serendipity Singers, as they all acted out their assigned role in "Potatoes in the Paddy Wagon". Not to mention the shmaltz and corn that all those "demented 6th chords" or whatever added to "Never Did No Wandering". A band like that deserved a manager that never really liked folk music - and back in the day they inevitably ended up with one one. Too bad we never got to see them play behind the strippers, which was another one of those inevitable "career moves".
