Hey das, I hear what you're saying. Overall setup wise, I bet this shot is quite similar to your typical GAOP Pirate beach debauch. Minus the clothing and hairstyles, etc.
About dancing - keep in mind that it wasn't until the late 19th century that men dancing would be looked on as "fairy" and something they would avoid. On the contrary, back then it was the pinnacle of revelry and something everyone would LOVE to do at every opportunity. Remember, in the GAOP era, MANLY men wore silk stockings, heeled shoes with buckles, wigs and even makeup on occasion!
Course these fops were probably called dandies by the rugged Johnny Punchclocks of the time (Sailors) but it was still considered masculine fashion.
