Routinely cited as one of the funniest movies of all-time, This Is Spinal Tap is much imitated, oft-quoted, and as fresh now as it was when it first appeared in 1984. If you haven't seen it, you must buy it immediately.

Directed by Rob Reiner, it takes the form of documentary following a shambolic heavy metal band as they tour North America. Though the band is, of course, fictional, their songs are very real, and very funny.

One of the men behind both these songs and the razor-sharp script is writer, actor, director and musician Christopher Guest.

As we'll discover, Christopher's musical background stood him in good stead for Tap, and also A Mighty Wind, his affectionate parody of the folk world. His latest directorial project is Mascots, in which he appears alongside Parker Posey, Jane Lynch, Chris O'Dowd and Ed Begley Junior among many others.

As with all his films, there's no traditional score - with the tunes the mascots perform to provided by CJ Vanston. But he is a fan of film music, and in particular the quirky orchestrations of Italian legend, Nino Rota.

Expect plenty of music from Tap, The Folksmen and Mascots, as well as the odd trip-down-memory-lane clip too.
