He hasn’t made a record since 1970, but the Syd Barrett legend continues to grow. Narrated by Newsnight’s Kirsty Wark and first shown as a BBC documentary, this serious-minded 50-minute film examines the legacy of the Floyd’s original Crazy Diamond, mostly through interviews with former band members Dave Gilmour, Rick Wright, Nick Mason and Roger Waters. They paint a harrowing picture of Barrett’s disintegration, although the Madcap himself is reduced to a ghost-like presence, seen only in a few flickering frames of archive footage. That it feels like a tribute to someone long dead only emphasises the overwhelming sadness of Barrett’s fate.
