Ashes to Ashes

ok, so I've watched all three seasons on DVD now and I must say it was a good conclusion to the story arc begun in Life on Mars, one small thing though I'd have had a cheeky little cameo by a Sam Tyler look alike near the end in the bar, just a brief glimpse of him through the door supping on a pint, oh and anotheinr thing I wouldn't have had them playing Life on Mars either, it'd have to be Ashes to Ashes for me, as the story was about the characters from that show moving not LoM as they'd already moved on...
