David Hasselhoff, Bruce Willis, Steven Seagal, Paris Hilton… to name just a few. Come on, seriously, what were you thinking?
Just stick to what you are good at: acting for some (?), being useless for others - did I heard Paris Hilton in the back row?
and Eddie Murphy's "Party All the Time" is an awesome song...
and the latest Shatner record has some GREAT songs on it, like "Common People" and "That's Me Trying".
Some music artists who succeed in music are actually no better than some of these people. It's just that once you are known for acting, the second you try out music you are scrutinised far more than anyone else would be.
