Jack Johnson and his son were spotted out riding their bikes in Oahu on Thursday. He and his wife, Kim, and three children live on the Hawaiian island, where Jack was born and raised. He's hanging around near home during a break from his world tour since he was forced to cancel the remainder of his Japan appearances due to the earthquake. The singer will be back on the road in May though, to play in South America, Spain, and Italy. Jack's travels mean that the annual April music festival that he and Kim founded will be put on hold this year, after six successful events.
