''Oh Anna''

[TheBang]

So, I looked into this, and it looks like what the deal was is that Karl was obsessed with an unreleased live version of "Anna" by John Martyn.

He talked about it on his diary here one day.

And then he played it in several DJ radio shows that he hosted, including one in 2005, and this one in 2012.

If it appeared at some point on their MySpace also, it was probably that same track because of his obsession with it.
