Anything Beatles / Led Zeppelin / British Rock Bands related (Staines-upon-Thames TW18)

I have a friend who actually worships both bands in concert but never kept any memorabilia. His memory is fading (after being attacked) and he is currently in a care home (in Staines). I'm just hoping any type of British rock'n'roll memorabilia would help his memory loss and hopefully bring a smile to his face again!
