It will be interesting to see if MK is a named performer at this concert but I suspect he will not be. Few of the performers named so far are true contemporaries of MK. Many are older and from a previous generation of musicians. Some are younger. I guess that Elton John and Annie Lennox are the nearest in age. The organizer is Gary Barlow and you MK fans will correct me if I'm wrong but I know of no link between and MK. Also, Mk has not been in the British public's conciousness in the way these other artists have been - that is, having hit singles, topping the singles charts or, for example, appearing on Top of the Pops. DS were more an Old Grey Whistle Test band. I'm talking Britain here not world-wide success.
Maybe MK will be added but, if it does happen, more likely as a guest guitarist rather than fronting. Then again, maybe I'll be wrong. Maybe Crockford and his team will pull some favours to get MK on the bill.
