Staying alive??

I went on a one-day First Aid course, courtesy of the National Trust.  It was a really interesting day, and one of the things we learnt was CPR.  I think the general idea is that the chest compressions are done to the tune "Staying Alive" (Vinnie Jones did a video using this idea) but one of the team sings "Nelly the Elephant".  I liked the idea of timing the compressions to Elton John's "Better off Dead" which actually works very well but maybe not the most appropriate tune!
