As a matter of interest, I suspect that there are at least two "London" versions of the soundtrack of "Evita".

The original version was unusual insofar as the record was released before the show was ever staged. This is the one where Julie Covington plays Evita. Many of us were disappointed that Julie didn't get the stage role, which went initially to Elaine Paige.

And yes, it does rock - the best thing Lloyd Webber has done,IMHO.
