Sometimes referred to as “Joseph Riddell”. “John” seems to be the more widely used name.

SCDDB internally has "John (or Joseph)" which may help with searches.

<<https://my.strathspey.org/dd/issue/3317/|Issue 3317>> explains that confusion appears to come from Gow attributing Riddle’s tunes as “Jo. Riddle” instead of “Jno. Riddle”.

A collection of John Riddell's tunes is available for free download (with optional donation) from the <<ddp:Highland Music Trust#10707>> via <<https://www.highlandmusictrust.org/the-john-riddell-collection>>.
