^^^^How is it pathetic? Its not like they are singing backup for their father. I think the son is A&R for some label and the daughter has her pop singing career.
I don\'t see any difference from when a father is in politics(Kennedy, Bush, etc.) and the kids get into it. Its about using the same connections that are already there for you. If you were raised by a pro baseball player and lived your whole life watching him play are going to games, it is highly likely that you will develop an interest or ability to play the game. If thats the case why do a 180 and sell car insurance?
