you know when you listen to the album that all those perfect performed songs aren't the original recordings. When you listen to some of Brian's boots, you'll hear the differences. Though it was a fantastic band, this is not real. Every solo from Brian is perfect on Live At The Brixton Academy. I always liked the way Brian tried to cover his mistakes when he plays live. It's just his charme. He's always trying to do the best he can.
So, I definately know for sure those recordings haven been edited and overdubbed.
You ain't seen nothing 'till your down on the muffin...;)
