Indeed. There's also a fun nod to the original E.T. at the 5:52 mark (both in vocals and choreography!), during the Katy Perry "E.T." song. Josh Greene loves to pepper his arrangements with fun easter eggs that pull everything together!
I got to meet Kentucky at Show Choir Nationals in 2010 and spent some time getting to know him and the other leads Sevi and Mary Lou at the Wild Horse get together. The funny thing about Kentucky is that he is such a dynamic performer on stage and so extroverted and demonstrative, but off stage he is the exact opposite. He was super quiet and reserved.
