I'd been asked some questions about Wish You Were Here (Pink Floyd) recently and have put my own version up on YouTube. It's very close to the guitar, but with some mandolin liberties (and also some liberties for faulty memory, as I don't think I'd played it on guitar in 15 years).
The octave is my new-to-me Kimble OM. If it looks familiar, it's the one Compton was playing the last couple years.
Wish You Were Here (with a bit of Fearless at the beginning)
