This is a tune I really like (so much that it surprises me I'd never made a video of it before). It's "The Hole in the Wall", which is attributed to Purcell and also appears in Playford's Dancing Master.

The sheet music for this melody is in my pdf book of traditional repertoire for viola, available at http://folkviola.co.uk – this tune is in Volume 1 (here's a direct link to the sheet music purchase page: https://payhip.com/b/Stru )
