Art Falls
This terminally obscure disc by Art Falls (Archie Wigfall) is the only one I know by this artist. But his vocals are particularly well modulated especially when he hits those high notes at the end of some phrases. And also as he gets grittier through this tender ballad 
I’ll Be There. The Nautilus label may well have come from Pittsburgh.
The bouncy flip “I Want You Baby” has some more Falls hoarse tones and by the style this 45 sounds as though it was recorded around 1963 / 4.
