A career retrospective fondly remembering a previous career retrospective: who said pop will eat itself? – Always Look on the Bright Side of Life, Live!) Rarefied name-dropping of the type indulged in tonight (a King Charles here, a Mick Jagger there) can sometimes pall. We get a handful of Python sketches onscreen (Nudge Nudge; the Queen Victoria Handicap), and a clip of the interview when the team “accidentally” spilled Graham Chapman’s ashes on live TV. If at times it’s not just nostalgia but nostalgia-squared tonight, at least Idle has a lot worth being nostalgic about.
