Wednesday Night is a fabulous 16 bar tune recorded as a ‘Country Dance’, and it exists in both the English and Welsh traditions (as Nôs Fercher in Welsh). The earliest record of it I can find is in a collection by William Clark of Lincoln published in 1770, though it seems to turn up in a few different collections at around that time. Here’s the tune, harmony, bass line and chords – I’ve not written out a separate chord chart due to the way the chords fit with the rhythm of the tune. I’ve also added a version with suggested phrasing and ornaments.
