All that can presently (May 2013) be gleaned about by internet searching is that S. C. Biddle is the one-off composer of In the Valley Where the Robins Used to Sing (1908) published by Judson & Jay Music Co., Williamsport, Pennsylvania, USA.
Surfers are welcome to contribute information about this composer.
