Sorrento By the Sea

If that link doesn't work just go to their home page and do a title search for "Sorrento By The Sea", or alternately Max Rosen. What seems to pop up for me is that Max Rosen is listed, but using a pseduonym "Reginald Dudley Morgan" for whatever reason, as their songwriting credits are identical.
