I saw this post at Boltas blog this morning and it got me thinking about some of the concerts I went to when I was younger. I found the clip below on youtube. It's the Bee Gees at Festival hall in Victoria. The blurb says it was filmed in 1971, I saw the Bee Gees at Festival Hall in 1973 and looking at the fashions the band are wearing I reckon that this was filmed at that time. From what I remember it looks like the same concert.
This may not be as good as the studio version but I reckon it's close to the Bee Gees best song. If you look around the stage there isn't a tattooed fuckwit in sight.
