How many Jonas Brothers are there? If you answered 'two' you're wrong, and we're guessing you don't remember the Jonas Brothers at the start of their career. Nick and Joe may be the ones who still have entertainment careers now both separately and together, but all the way back at the start of their fame there were four of them. The third was Kevin Jonas.
The problem with being a successful musician is that you spend a lot of your life on the road touring. That didn't sit well with Jonas after he met and married the love of his life; his wife, Danielle. Kevin was always the older of the brothers, and therefore the most likely to settle down first. That's precisely what he did, quitting the band and setting up a construction company instead. Now a husband and a father of four, he clearly feels there's more security in building work than there is in worrying whether anyone will buy your next album.
