Jeans on TV

My friends call me old fashioned, but if I was on national TV I'd dress up. Last night on the World Series on Fox, Ozzie Smiths son sang the National Anthem in JEANS. The former American Idol, who sang great by they way, should have worn better attire. He wore a World Series jacket, ok plug where you are fine. But jeans? I was taught when you sing the Anthem you show respect, and that includes how you carry yourself. To sing the anthem on TV? Again, I'd think that would call for people to dress up. Maybe I am just old fashioned....
