not sure why grace jones was included, and cheryl cole is an embarrassment. As to status quo, they are usually included in these gigs perhaps the old boys are having a bit of a rest.
Status Quo would have only needed to play one number as every one of there records sounded the same IE same music slightly different lyrics. Anyway it's unlikely you would see them in June they only perform around Christmas time whilst doing their annual farewell tour !
'Madness' performance was good I thought, the decor during their singing was even more amazing, the changing scenes on the Palace front was really cool!
