Sources: CJS MSS (via GF and RD). Sharp's information was from John Inward, dancer and musician, who 'danced with great vitality and spring ... throwing his legs further and therefore higher than morris men are used to do, and keeping them very nearly straight, though his hip-joints were wonderfully loose and flexible'. The dance is, in construction, interestingly intermediate between Cotswold and Border Morris.
The music: was by fiddle; Inward's (given to him by his 'father's granfer') was half-size. He said the tune here given (a version of Old Mother Oxford) was the only tune the Steeple Claydon Morris dancers used.
