This was pretty cool.

It was already cool that Lancaster kid, Dan Mertzlufft was going to be on The Late Late Show with James Corden, but the surprise that they had ready for Dan was incredible.

Dan made a video on TikTok that was blowing up after he posted an original song of his 'grocery store musical' and people were loving it and responding to the video using the duet feature to sing alone with Dan. James Corden loved it so much that he invited him to the show, but what he did not expect was to see his song sung with some of the most famous Broadway performers. There were roles played by Patti LuPone, Kristin Chenoweth, Audra McDonald, Josh Gad and Josh Groban. Take a look here.

James is such a fan, that he even predicts that Dan will be writing his own Broadway show in the future. Good work, Dan!
