HHH made Vince McMahon to Change his Mind About....

The original plan for Cesaro to have no theme music was going to last a few weeks longer, as it was a Vince McMahon idea, but Triple H talked Vince into changing his mind. It was said that Triple H hated the idea of Cesaro coming out to no theme song.
On a related note, the idea to align Cesaro with Heyman was something they came up with on their own and pitched to Vince. Vince loved the idea so they went with it.
