Other forms: lineups
A lineup is the set of people or acts chosen for a team, a show or a police parade. Who is in, and in what order.
Sport uses it for the selected side, music festivals for the bill of performers, and policing for the row of people a witness is asked to look at, which British English calls an identity parade. Announcing a lineup is a real event in each case. British English usually hyphenates it as line-up. The verb line up means to form a queue or to arrange something.
