Aidalai is an album by pop group Mecano. It was released in 1991 and produced by the group. Its launch was in the middle of rumours of the separation of the group due to differences between Nacho Cano and José María Cano. It was their third release with Ariola Records. The title is a play on words: Aidalai → ¡Ay Dalai!, meaning in English something like Oh Dalai!.
