Anyway Dusty, I won't worry very much about Clark. He would only go if they are to perform, and that looks unlikely.
This is the part about Alan Clark in the article
Clark, who's now in the band Legacy with several other former Dire Straits members (its debut album, 3 Chord Trick, came out in November), says he's reserving his commitment to attend the ceremony until the group's plans are determined. "I'll go if there's a reason to go, if Mark decides he wants to go and put something together and go and perform there," Clark explains. "Jump back to 1992, the last gig we played in Spain, I said, 'That will be the last gig we ever play.' When people say, 'Will the band ever get back together, I always say no. But will we get together for this? I don't know. I'd be totally into the idea of it happening."
