During the half-time of the Knicks  loss the 76ers last night, a Knicks's Garden of Dreams Foundation performer got some surprise assistance by J.R. Smith who came out of the locker rooms early to play the air guitar while she sang the Lumineers' "Ho Hey."

Smith will probably get blasted for this along with missing 11 of his 16 shot attempts but I'm glad somebody showed the girl some appreciation.  The crowd was as enthusiastic as the security guy in the bottom right corner of the video.
