Mr. Barrett is well-known to fans of 'Doctor Who' for his seminal role as Koquillion in a 1964 two-parter called 'The Rescue' ("It is Koquillion! You can't come in!!")
He's also known to cult TV fans as many of the voices in Gerry & Sylvia Anderson's 'Stingray' and 'Thunderbirds'. The latter he provided the voice of the Duchess of Royston in the episode 'The Duchess Affair'. Viewers of 1970s television will also recognise his face as one of BBCTV's 'The Troubleshooters'.
The LP is titled 'Large as Life' and he gives a creditable account of himself as he sings his way through a selection of ballads and love songs. The title track is the only let down. Much of it is spoken in the voice of the Mighty Titan from 'Stingray'. It sounds odd and I still can't quite fathom what it's about - something to do with a 'larger-than-life' lady he once knew.... or something!
Anyhow, back to my point. There were quite a lot of these sort of LPs produced by the top TV stars of the 60s and 70s including Stuart Damon (from ITC's 'The Champions') and a rather disturbing offering from TV's Jason King alias Peter Wyngarde. (The track entitled 'Rape' is not to be listened to under any circumstances!).
Some of the cast of 'Doctor Who' attempted to release LPs highlighting their vocal talents but sadly none of them were ever available in good record shops.
