I do not suffer fools gladly.
This is an unusual example. The video above is the original, when Heidi, a lyric coloratura, was lead singer of the band. When she was replaced by Capri, a dramatic soprano, the band released a new CCD called Re-Evolution with Capri's vocals replacing Heidi's. This is a somewhat rare event. Below is Capri's version over the exact came instrumental tracks.
The songs from Re-Evolution are some of the only examples of how simply changing the vocalist can make a major difference in the overall sound of a song.
