Apparently, the first time Sir Elt saw Stephen Daldry’s acclaimed Brit flick Billy Elliot at its Cannes premiere he wept with recognition. Indeed, so moved was he by the tale of the young miner's son who just wants to dance that when the idea of turning it into a West End musical was mooted, he leapt at the chance to provide the music.

Electricity is the first song to be released from the resulting soundtrack. It's a touching account of the release and passion that Billy feels when the music takes hold of him and he starts to move - the boy's feelings plausibly and poetically evoked by Lee Hall's suitably theatrical lyrics.

This song was, by far, the highpoint of Elton's contribution to the stage show. And while some of his material was justifiably criticised as being merely serviceable, that doesn't apply here. What jars, however, is that this song was intended for the show's young protagonist, and with Elton on vocal duties it somehow loses a lot of what made it so powerful in the theatre; Elton's voice, though on good form, just doesn't fit the lyrics. On stage this song is a glowing moment in what is undoubtedly one of the most exciting shows to open in the West End this year; out of context it falls a little flat.
