There's a Youthmovie Soundtrack Strategies/Redjetson split 10" on blue vinyl (released by Drowned in Sound Records) in Oxfam in Angel.
Saw it and didn't buy it. I plumped for 'Blue for You' by Status Quo instead. Sadly, this did not come on blue vinyl despite the title.
On a side note, charity shops (or at least Oxfam) are getting bloody expensive these days.
