Song bridges Charles River

This year’s RiverSing at the Weeks Footbridge was, as always, a festive affair with music from a variety of lyrical sources, including the Halalisa Singers and saxophonist Stan Strickland. Chiming along were bells rung by assorted visitors. Of course, there was the usual dazzling appearance by the gargantuan puppets Oshun and Poseidon. The music, the color, the weather — all conspired to make this autumnal welcome a success.
