Graham “Suggs” McPherson, gawd bless him, has gone from being the naughty boy from a nasty school to pop legend as the frontman to Madness to a bona fide national treasure. This film by Julien Temple, essentially a lightly padded and playfully embellished concert movie about Suggs’s autobiographical standup show, trades heavily on the geezerish goodwill that still surrounds him. And if Suggs’s anecdotes are not quite as entertaining as he thinks they are, it hardly matters, such is the disarmingly raffish charm of the delivery.
