It started with Michael Thornton, Principal Horn of the LA Chamber Orchestra, doing his one-man, four-part rendition of “Take Me Out to the Ballgame.”  The social media folks at LACO tweeted it out with a cheeky  question directed at Houston’s River Oaks Chamber Orchestra:  “You got anything?”

Um, Game On, ladies and gentlemen.  Game.  On.

Soon after, ROCO tweeted this retort, featuring Matthew McClung, their principal percussionist:

Go Dodgers!
