This doesn't come as a huge surprise, to be honest. Jeff Buckley's mother Mary Guibert has said that her son was a massive Smiths fan, and viewed Morrissey as a bit of a legend. He occasionally covered 'I Know It's Over' in his live sets, in fact, and a single featuring one of those versions is set to be released. I have to confess to listening to that track on repeat back in the day.
On the release of the track, Guibert says: "Jeff was a huge Smiths fan. He thought Morrissey was a living legend, so this song was a very meaningful choice".
Guibert went on to reveal her plans for the future release of more of her late son's material: "My philosophy is to allow Jeff's legacy to grow on a grassroots level with an orderly release of work, rather than letting it all be dumped on the market at the same time. Folks have seen that, and it has paid off - and I am very proud of that".
