Talking last night to my mate who works in a record shop, it appears that there are no physical copies of any of Amy's albums available, apparently Island had minimal stock which all got exhausted on the day after her death, and now you'll really struggle to buy a copy anywhere. I don't doubt that they're scrambling desperately to press more, but if you want to commemorate Amy's passing by lining Island's pockets then you'll have to download the albums.
I'm always intrigued by the sudden rush to purchase music in the wake of an artist's death. I guess some copies go to fans (to keep pristine as mementoes, etc) but surely the vast bulk are sold to people who never bought the artist's songs when they were alive. I find this ghoulish, as if the songs suddenly have some deeper meaning in the context of the artist's death. That said, mind, I have a gargantually appalling record by John The White Rapper (yes, really) which features an uncredited Amy on the choruses, and I'm going to sell it for a newly vastly inflated sum to a chump. Hurrah!
Gumdrops - Mick Hucknall poured loads of his own cash into Blood and Fire, the reggae/dub re-issue label, so he's alright by me.
