It runs in the family

My Mum recently attended a party which required her to dress as someone or something in a Beatles song. No, not a Beatle (that would be rather limiting) but a fictional Beatles-inspired character. What a damned good theme! Difficult though. Think it might have been better to have allowed people to come as someone or something from any song. But anyway.
My suggestions were:
Polythene Pam (although as Mum pointed out she's so good looking but she looks like a man - and there's something about jack boots and kilt going on too. Not a very flattering look)
Lucy in the Sky with Diamonds ( we thought everyone would do this though)
Paperback Writer? (You could pick a famous writer, see, and go as them)
Her Majesty? (either Maj herself or some other Queen)
A chauffeur (from Baby you can drive my car?)
Lady Madonna (either by tying children to her feet - ahem- or perhaps a Ciccone stye get up?)
There's a whole cast of people in Penny Lane to be plundered... or some circus freaks from Serjeant Pepper's Lonely Hearts Club Band.
Her friends had already picked out Desmond and Molly from a market stall.
Anyway the upshot was she went thus:



Yeah
And she don't care.
