However, about half of the dances in the modern Scots cèilidh are couples' dances performed in a ring. These can be performed by fixed couples or in the more sociable "progressive" manner, with the lady moving to the next gentleman in the ring at or near the end of each repetition of the steps. In Ireland, the similar style of dance is called cèili dance or "fíor" (true) cèili dance. Some of the dances are named after famous regiments, historical battles and events, others after items of daily rural life. The "Gay Gordons", "Siege of Ennis", "The Walls of Limerick" and "The Stack of Barley" are popular dances in this genre.
