Live performance of Matsumura's debut song from 1980. A subbed video will be posted later, here is part of the lyrics as a teaser ;)
She is voicing te feelings of a young man whose girlfriend is leaving.
--COME BACK TO ME--
On Iwakisan Mountain, I told her, "Make sure to return to me."
And she nodded quietly.
Did you forget our promise in a busy life in Tokyo?
Return to me, return to me, return to me
