The track is called 'Strange & Beautiful (I'll put a spell on you)' and is by Aqualung. Aqualung are currently unsigned, so as such there are currently no plans to release the track. However, with all the interest that there is in the song at the moment, I would've thought that this situation will change pretty soon. Aqualung features/is Matt Hales who is lead vocalist of The 45s. More information about the 45s can be found on either their official site at www.the45s.co.uk or an unofficial fan site at www.ispythe45s.btinternet.co.uk
On the latter of these two sites, there is more information about Aqualung and the song, as well as an mp3 of the song to download, and information on how to join an Aqualung news mailing list in order to be kept up to date with all the news as it's announced.
