What is it with 1970s rock bands and the Internet? Yet another example of social networks and Web 2.0 coming to the rescue of a faded rock group: legendary band Boston is starting a tour this summer, and one of the stand-ins for missing singer Brad Delp (who committed suicide last year) will be a guy named Tommy DeCarlo, who the band found via cover versions of Boston hits that he had posted to his MySpace page. I can't find out much about DeCarlo, but he's actually pretty good at hitting the spine-tingling notes that Delp was famous for.

Boston joins another rock band with long hair and a high-pitched singer: Journey, who parted ways with original singer Steve Perry and then later parted ways with his replacement as well. Then they discovered a Filipino fan on YouTube, and he is now touring with the band. And to round out the trio, the thrash metal band Anthrax also found a new band member in part through MySpace. And of course INXS found a replacement for their singer through a reality show called Rockstar INXS, which isn't really social media but is pretty close. If I were a singer or guitarist for a fading rock band, I would behave myself, if only because I would be afraid that my fellow bandmates could replace me with some yob they found on MySpace.
