Last month, Dan + Shay were supposed to open for Rascal Flatts in San Diego. Unfortunately Rascal Flatts had to cancel the show due to illness. Dan + Shay didn't want that to stop them, so with a little help and some phone calls, they had a pop up show at the House of Blues! How cool is this!?!?! They actually called many fans on their own to invite them! Dan + Shay....classy, kind and great for Country Music!
