The music and Bathsheba

Does anyone know what that lovely music was that they were dancing to in Boldwood's house? Was it an old traditional English tune?

I liked both this version of FFTMC and the 1967 one. I think Carey Mulligan would be more what Hardy had in mind as regards the look of Bathsheba.
I found the part where she was wearing trousers and what looked like pirate boots when she threw her leg over the horse a bit too modern. I felt it was catering to a modern audience. I know in the book she does ride the horse like this but it felt too aimed at today's audience.
