> 'Shoals of Herring' has a Roud number, as does Jimmy Rodgers' 'Away Out on the Mountain'

A fragment of "Shoals of Herring," at least, was collected (naively) by H. P. Beck as a traditional song from an Irish singer who, apparently, hadn't learned it from a record. Beck wasn't infallible, and neither was his fisherman singer who knew only part of the song.

Nor has anyone suggested that Steve Roud is infallible.

Even if he *has* done some of the most important work in folk/trad scholarship of the past 50 years.
