If I recall correctly, Jeff mentioned, a while back, to me that the 'Forever Autumn' video, that some remember seeing on The Multi Coloured Swap Shop back in 1978 (and yes, I am one who remembers!), was also made especially by the BBC to accompany airings of the single.
This is one of the reasons why it is impossible to make these videos available for download on this site, alas.
