Night Job

I've noticed something over the past few years that I've been working at my current job. Being an entertainment related company, several of my co-workers are in bands, make movies, play instruments, sing, act, dance, etc. I see them posting flyers all over the office for their gigs, movie releases, art shows, etc. Now why don't I have a night job? So that I can then go to that night job and say how much my day job sucks and that my true passion is what I do after I clock out at 5. LOL Maybe it's time I dust off that old Casio Keyboard from the 80's that's been forever under my bed. ;)
