In reply to mike123: See i m in a very convial hostelry enjoying a few fine pints of very fine gold , and a friend of a friend comes over and asks the above question , I say "it's something like Cham bus " I google that and get no joy , so say " I bet some one on ukc will know " , would it really have been too much trouble to type nothing more than Cham express , ? Obviously not . Have a good weekend , mines starting off well .
