I forgot it's Pepsi Twist which is the decent lemon-flavoured-cola and not "Diet Coke with Lemon flavour" which tastes like something you use to clean your dishes.
I got home to find two Doctor Who Unbounds (Auld Mortality and Full Fathom Five (Yay! David Collings and Ed Bishop!)) and Flip Flop, featuring the lovely Bonnie Langford. The latter is in a rather odd looking cardboard case.
My only dilemma now is which one to listen to first.
