Can you play more than one brass instrument?

I'd like to congratulate the organizers of the Singapore Brass Explosion this weekend. I had the chance to give master classes and perform along with some of the world's finest brass players. It was an uplifting experience and a lot of fun!

We had the privilege to hear the fantastic James Morrisson who plays trumpet, trombone, euphonium, saxophone, piano and god knows what and is absolutely amazing at everything! If you don't know him, go on youtube. There's got to be a bunch of videos of him.

It reminds me that when I was in school, we were told not to play on other instruments than our own because it would apparently ruin our embouchure if we did. After hearing James Morrisson, I'm not so sure anymore! Maybe he's just one of his kind but I guess if he can do it, it's possible. 

Fooling around with a different instrument (we all did it anyway!) might disturb your chops for a few minutes when you go back to your own horn but I doubt it would ruin them! And for what I've seen this weekend, it is possible to become a virtuoso on all instruments if you're willing to practice all of them! I just don't know many people with the talent, time and resources to achieve that!
