CLEVELAND (AP) - It's one thing to play "God Only Knows" by The Beach Boys at a wedding. It's quite another when it's The Beach Boys themselves singing it and it wasn't part of the plan. The Cleveland Plain Dealer reports The Beach Boys were sound-checking at Jacobs Pavilion at Nautica while Mark Kent and Jaime Diadium exchanged vows next door. The couple weren't upset and in fact consider it their official song now. The band caught wind of the incident and as an apology told the wedding guests they could come over for free. The bride wandered over just as the show was winding up, and the band brought her on stage as they performed "Fun, Fun, Fun."
