They need to hurry up and use him as he aint getting any younger

If he is replaced, i think the possibilites are:

Linda Evans (shes the only one i thought would go in & didn't)
Marcus Collins (more likely as a young male)
+ a dream one (realistic-ish but not if its last minute)
David Hasselhoff (he did the german one)
Or someone else from baywatch

& at the back of my head i can think:

A sports star like nicola adams (there isnt any in there so)
Alan Fletcher
oh & i nearly forgot THE WEALDSTONE RAIDER!!!!
