What connects Stephen Hawking, David Bowie, Galileo and Elvis Presley?

What a day! Stephen Hawking, David Bowie and Elvis were all born on the 8th of January and Galileo  died on the same day. Interestingly, I see that the Pope has just announced that God was actually behind the Big Bang so some major revisions now required to Genesis, I suppose. Came a little late for Galileo but better late than never.  Anyway in honour of these esteemed gentlemen (excluding the Pope) I have gathered some videos to hopefully honour the connection.  Not much on YouTube for Galileo so I settled for Declan O'Rourke instead.
