Luke Winslow-King Performs on Episode of CBS's NCIS

*Double-take* Was that Luke Winslow-King performing at the end of the new NCIS episode on CBS last night? Why, yes; yes it was. 

Luke performed an original piece to close out the show as the crime team kicked back in a park in New Orleans...probably looking for meddling musicians up to no good. 

You can see and hear Luke at the 38:00 mark here.
