There wasn't a live album officially released during the lifetime
of the band. However, Mirror Man was
recorded live (albeit in the studio) and some shows were recorded
with a view to releasing an album - the 1974 London and 1981 Reseda
shows for example - but nothing official came of it.
Thirty two years after the event Virgin finally decided to release
their recording of the Drury Lane, London show of 1974.
Otherwise the closest we have to official live albums are the Rhino
release of the 1978 My Father's Place show or the 2006 release of
Amsterdam '80 which had both been recorded for a radio broadcast.
Apart from that there are only a few 'grey' releases (listed below)
... and, of course, the bootlegs
