By his own admission, Paul Simon had some very lean years between his 1975 classic Still Crazy After All These Years and 1986’s multi-million selling, multi-Grammy-winning Graceland. His 1983 album Hearts And Bones was a major flop despite featuring some fine songs and great musicianship.

But the real nadir was ‘One-Trick Pony’. I stumbled across it very late at night on British TV in the late ’90s and was instantly gripped. It’s that special kind of crap movie – the ‘rock star’ vanity project with a gallon of overreaching ambition. To say it hasn’t aged well would be a huge understatement, though, as with most genuinely bad films, it features a myriad of guilty pleasures too…

In 1980, Simon clearly wanted to celebrate his new Warner Bros record contract with a bang (he’d just jumped ship from CBS) but who persuaded him that a self-written, autobiographical movie was the answer? His screen persona was hitherto based pretty much on one (admittedly superb) cameo in Woody Allen’s ‘Annie Hall’.

But in ‘One-Trick Pony’ he tried to carry an entire movie with just two default settings: he’s either bopping around the stage, sweaty and somewhat bug-eyed, trying desperately to ‘rock’ (in Joe Queenan’s memorably cruel words, Simon is ‘too short to rock’n’roll, too young to die’), or he’s sulky and morose, peering doe-eyed into the middle distance, desperately trying to be adorable.

Simon plays Jonah Levin, a once-popular folk-rock artist who has fallen on hard times (see what he did there?) and now reduced to hawking his band (Steve Gadd, Tony Levin, Richard Tee and Eric Gale) around the Midwest, supporting bands like the B-52’s (who are held up as an example of the ‘hideous’ way the recording industry is going, but whose schtick is so much more vital and life-affirming than Simon’s supposedly ‘raw’ music…).

Jonah’s relationship with his estranged wife – Blair Brown in a completely thankless role – is terminally dull, with undramatic longueurs and clunking one-liners. There’s also some excruciating stuff with Jonah’s ‘cute’ son. You know the kind of thing – lots of ‘whatever happens, Daddy loves you, OK?’-type dialogue and cloying shenanigans with baseball mitts and copying Daddy shaving at the mirror.

From a muso perspective, you might well ask how a movie so heavily featuring superstar players such as Gadd, Gale, Tee and Levin can be outright crap. Well, the novelty effect lasts a few minutes but after that you can only feel for these gents – they’re given pretty thankless roles, playing a fairly tasteless ‘dead pop stars’ quiz in the car, reading out gig reviews and endlessly checking into dodgy hotels. Poor Richard Tee and Eric Gale look the most uncomfortable.

Jonah’s dealings with the record-biz ‘suits’ in ‘One-Trick Pony’ are presumably based on Simon’s disagreements with his previous employers CBS Records, and they produce the only enjoyable sections of the film. Rip Torn is reliably gruff though resolutely uncomical in his impersonation of legendary CBS hatchet man Walter Yetnikoff, but Lou Reed clearly relishes his cameo as a jobsworth producer; he’s desperate to add strings, horns and backing vocals to Jonah’s stripped-down tracks. Cue a lingering close-up of David Sanborn letting rip on alto, though we’re never sure if this is meant to be a Bad Thing or even a joke – to this viewer, it seemed like the first bit of decent music in the movie.

Oh yeah. The music. The soundtrack of course did a hell of a lot better than the movie – great single ‘Late In The Evening’ featured a Steve Gadd groove almost as influential as ’50 Ways To Leave Your Lover’ and even made the top 10 in the States.

To be fair to Simon, he had sorted out his screen persona by the time of the ‘You Can Call Me Al’ video in 1986, settling on a kind of faux-naif ‘everyman’ figure with some aplomb. He was also pretty funny in Steve Martin’s ‘Homage To Steve’ short from the same year. But let’s just rejoice that he hasn’t returned to the world of feature films since (or has he? Ed).
