Thank you furrypussycat will have another try.
82 Grange hill initials L M.
Have answers for 74 & 68 but several people have helped me so don't know how they arrived at them so will just have to say 74 Will Smith & 68 Aimee Duffy.
Hope this helps & good Luck.
Thank you birdie73. Found Grange Hill haven't found exact pictures for other 2 though but can see similarities. Will go for them if nothing else comes to mind. Good luck to you also.
