Swing Cats While most of the swing cats do not have official names, they do have their own destinct costumes. Their rarity makes them mysterious and fascinating. Sometimes they appear in the group cast photos. The most well-known London Swing cat is sometimes called "Nameless Brown Queen", "Hisperia", or "Summer" - in honour of Summer Strallen, who wore the costume in the final London cast. Both Summer's parents, Sandy Strallen and Cherida Langford, were in Cats, and her aunt, Bonnie Langford, was Rumpelteaser in the original London cast, giving Summer a definitely feline pedigree!
