Believe it or not DAVE is a serious jazz musician...but he has an unusual sense of humour. He has a friend who was always asking questions but would be impatient for a response so he would always say "Dave" .."Dave".."Dave". One day, Dave had the idea of doing a fun song just for his friend....then people started to like it saying ..."do a video and get it on YouTube". 　　so that is where we are at the moment. you have to admit ..it is quite infectious...especially if you know a DAVE or 2...Lol
