It's a great night to be a Fray fan in New York.

The multi-platinum rockers played a very intimate, private show to 200 of their closest fans at the iHeartRadio Theater Friday night, rocking tracks like "How to Save a Life," "You Found Me," and "Run For Your Life."

"Piano player on a guitar, you never know what's going to happen," frontman Isaac Slade joked after he switched instruments for a performance of "Over My Head (Cable Car)."

The band's new record, Scars & Stories, will be available Feb. 7.

On Wednesday, we were lucky enough to catch a game-changing performance of How to Succeed in Business Without Really Trying featuring the incomparable Darren Criss!

But last night, Blaine Darren impressed us even more by bidding farewell to fans after the final performance of his three-week stint.

"For many years in New York City, I've been coming to every theater in this town," Criss told the hundreds who were waiting in the cold.

"I've waited outside hours for people, but I have never seen or felt the energy that has been given to me at all these shows."

We're kind of glad we weren't there, because we would have cried?

Check out Criss' farewell, above.
