Neither the Overture nor Fairy Day, Op.131 has ever been performed as far as anybody is aware.
According the Jeremy Dibble,
Fairy Day, written for Victor Harris and the St Cecilia Society of New York,
was premiered by it's dedicatees in 1913 and later performed by Horatio Parker in Philadelphia. Paul Rodmell, however, is of the opinion that the work was "apparently unperformed by [the St Cecilia Society]".
More likely somebody has sponsored the performances in some way. I've seen no other signs of Auntie suffering a Pauline conversion.
The broadcasts are taken from performances during last year's BBC Invitation Concerts at the Ulster Hall: I've found all the relevant dates and will put these into the file information when they're uploaded, together with the text of
Fairy Day.
