Mayor Peter Chin told the audience of about 1000 at the Age on the Go mayoral variety concert in the Dunedin Town Hall yesterday that a sing-along was his idea of a "healthy exercise regime"

"Dunedin is a healthy city and we want all of you to exercise. This sing-along is part of it," Mr Chin said before linking arms with the other performers on the stage as they sang You Are My Sunshine, Side by Side and I do Like to be Beside the Seaside.
