I'm desperately trying to find out a name of a song I saw on TV and I have a REALLY strong feeling it might be Hirakawachi 1-chome. Did they ever have a song where it was straight guitar and no singing (except random la la la's bye children and them) near the end.

In the music video, they are sitting on a pier and they just start playing guitar...then they get up and ride a bus and play with a baby...and then they're by the water again.

Please help if you know any thing about them or that song. Thanks SO much~
