This dance borrows the diagonals from Pat's Tradition (unless it came first?). The tune recommended for that is My Wife's a Wanton Wee thing. It would work well for this too I think. https://www.youtube.com/watch?v=9026vlPB6do shows how the crossings naturally leave you facing the right direction

Hello all! I've been meaning to chime in. Don't think anyone has mentioned this one. I would consider Beneficial Tradition by Dan Pearl has having an unusual sequence. A friend used the exact same words, gimmicky, when I called it. That term hadn't occurred to me until he mentioned it. Anyway, here it is and a youtube link:

Becket, double progression

A1  Ladies alle L 1.0 to form a wavy line; Bal wave, swing P
A2  Circle L 3/4, N swing
B1  Ladies chain, LLFB
B2  straight across with opposite sex, pull by left, face in (4)
on slight right diagonal, with same sex, pull by right, face in (4)
straight across, with opposite sex pull by left, face in (4)
on slight right diagonal with same sex, pull by right, face in (4)

The author advises: This one needs strong, clear four-beat phrases in B2. More driving or exuberant and not mysterious or in a minor key.

I think Brian Hamshar did an excellent job teaching this dance.
