Cover album?

Robert Smith of The Cure made an interesting blog entry for the official band website on the 13th of January.

I have recorded a cover for a John Martyn tribute album, as well as a couple or three other 'collaborations'.

So what we can tell from this is that someone must be producing a John Martyn tribute album. I have no further details yet and wonder if they will make it before the 29th of January.
Would be nice if they managed to get some people listed on this page...
