I find that when I have learnt a song , if I look back at the original words , there are phrases that have changed . I think this is because what sounds perfectly natural to one person is not comfortable to another so over a number of airings , the occasional phrase gets skewed to be more comfortable for me to sing , entirelt unintentionally !

And Janine , I have heard at least one version where the line is 'cast The Glamour' over her , as in 'Put a Spell on !
