Country fans know that Luke Bryan is a total pro when it comes to performing in front of thousands of fans. But when he performed the National Anthem during baseball’s All Star Game Tuesday night in Kansas City, there was speculation he may have used a ‘cheat sheet’ to help him navigate the lyrics.

And turns out those speculators were correct. On his Twitter account this morning, Luke admitted he did have “a few key words written down.” And he seemed genuinely apologetic about it.

Here’s his explanation:

Morning everyone. I really wanna explain the national anthem performance from last night. — Luke Bryan (@LukeBryanOnline) July 11, 2012

I had a few keys words written down to insure myself that I wouldn’t mess up. I just wanted to do my best. I promise it was from the heart. — Luke Bryan (@LukeBryanOnline) July 11, 2012

So yes, he did have some words written down. No crime in that, right? He simply wanted to ensure he didn’t “mess up” an important song, and moment.

If I offended anyone with my approach I sincerely apologize. Anytime I sing the anthem it is an honor and my heart beats out of my chest. — Luke Bryan (@LukeBryanOnline) July 11, 2012

Some fans speculated that he wasn’t looking at a cheat sheet but was checking his watch, so that the military flyover would time correctly with the lyrics. Apparently, that was part of his plan.

I did check my watch because I knew the stealth bomber would fly over 2 minutes in and I knew a started a little late. — Luke Bryan (@LukeBryanOnline) July 11, 2012

And the bottom line? He said the experience was “amazing.”

Being a part of the all star game was amazing and I look forward to the next time I can perform the anthem. Thanks y’all. Love ya — Luke Bryan (@LukeBryanOnline) July 11, 2012

Fellow country singer Jerrod Niemann was one of several artists who quickly chimed in to show support:

“@LukeBryanOnline: Morning everyone. I really wanna explain the national anthem performance from last night.” u did great! There, explained — Jerrod Niemann (@jrodfromoz) July 11, 2012

James Otto had a smart perspective as well, writing that “anyone who’s got a problem with it’s never had to sing the anthem in front of thousands while the thought of screwing up lands you on YouTube to be lambasted for all time. If he wrote it down he was smart.”

And we’ll bet that Martina McBride would probably have his back here as well. Having sung the National Anthem many times herself, she’s also admitted to having the lyrics within easy eyesight…just in case.

If you missed his performance, you can still watch it here. Nice job, Luke!
