The biggest mistake you can make in a rock band (or in any job, really) is to assume that you're irreplaceable. Lead singers are especially prone to making this mistake. After all, they're the voices behind the songs – they can't possibly be replaced, right? As Steve Perry, Vince Neil, Dennis DeYoung and many others have learned, they can in a heartbeat – and often by somebody younger with a similar voice who's happy to tour year round and never utter a word of protest.
That said, it's not very solid ground to stand on. The fans often long for the original singer, and the threat of a reunion is always hanging over their heads.
Here's a side-by-side video gallery of bands performing one of their signature songs with the original singer and their replacement. In some cases, the replacement has since gotten the boot, and in others they are still fronting the band.
