Song from tonight's Parenthood, "I need you now, I'm lonely..."?

I'm looking for a song that aired on tonight's episode of Parenthood, "If This Boat is A Rockin" - it played during the scene when the older siblings were in Crosby's boat and some of the lyrics are, "l'm lonely and i need you know, take my hand...save me." It is sung by a male artists and sounds like soft alternative.
