Jack are you suggestingSharp had a racist agenda?, this would have been out of keeping with hid fabian ideals, would it not is it not more likely that he only had the energy and time to collect songs from the geographical british isles and how they had evolved in appalachia

The article identifies some racist attitudes he expressed at times, not enough to constitute an "agenda". He just seems to have been remarkably indifferent to the un-Anglophone world. Grainger was closer to being an ideological racist but in his very selective way had a far wider awareness.

Bartok somehow found time to collect a larger number of songs just from outside the Hungarian sphere than Sharp got in his entire career. So it could be done.
