Shehan's Reel is a great dance for any age group. You need know nothing about heads and sides nor corners
A1 Women to centre (curtsey?) and back; men ditto (bow)
A2 Women star Right; women star Left
B1 Women pass current partner to, do si do and swing next man
B2 Promenade with this person and face in to start again
I usually put it with a break of " Circle eight left and right; All to the centre and back, do that again; dosido and swing current partner and promenade"
With the right group, the last 8 bars of the figure can be "promenade to another square!" and then start again with the break. It doesn''t matter if there's more or less couples in the new "Square"
It's a very forgiving dance!
Have fun
