I have sung the chicken dance for many dances and I just don't get why people like it.
It does fill up 5 minutes at the end of the night which is no bad thing for a band that is feeling a bit tired.

I like My Aunt Came Back Better

Oh my Aunt came back from Tokyo Japan and she brought with her a waving fan.
( Start waving your hand)
Oh my Aunt came back from old Algiers and she brought with her some clipping shears.
(Start clipping your hand too)
Oh my Aunt came back from Timbuktu and she brought with her a wooden shoe.
(Start lifting your shoe too)
Oh my Aunt came back from salt lake Eyre and she brought with her a rocking chair.
(Start rocking back and forward too)
Oh my Aunt came back from Guadalope and she brought with her a hoola hoop.
(Start circling your hips as well)
Oh my Aunt came back from Taronga Zoo and she brought with her some monkeys like you
(Point at all the people moving strangely)

It works with kids, it can't be too bad.
