Should or Should Not...

This question ponder me since my posting is out.Should I go for the MDC interview?
(MDC = Music Drama Company)
I have to make up my mind within hours as the interview or so called audition will start 5 hours later.What they want to see from me is 2 songs,a Chinese and a English,hosting acting and dancing which is done in-house + given script.I don't see any thing difficult from this.
Actually I am quite happy to be posted to SISPEC and I also know who is going with me.But should I go? *thinking*
