These Navy personnel are recruited for their musical talents. That’s their job. They come in at a higher rank (e-5,6?)than the normal enlistee. They are all music school qualified musicians. The announcer may be different, I didn’t ask him, but he gave me the other info. If you master an instrument, like the one guy who plays trumpet with one finger, I’m sure they find a place for you. You get to travel a lot. I was impressed with the show, us Army guys who were there loved it. The Army is coming next, lets see if they can match it. BTW, The Jersey Boys number rock the auditorium. They were other very talented singers too. If you get the chance to see them, go for it!
We have a guy who is a Navy recruiter who sings with the big band I am in, Steven Powell, who sings the Nat’l Anthem at some Raiders and Giants games. Sometimes the Phoenix Suns.
