"The song takes its name from the 1968 album Wonderwall Music by George Harrison, at the time still a member of the Beatles. Harrison's album was in fact a soundtrack to the film Wonderwall, but the film has remained unknown by the general public. The original title of the track was "Wishing Stone".
It is often claimed that "Wonderwall" was written for Gallagher's then-girlfriend, Meg Mathews. Noel married Mathews in 1997, but divorced four years later. Gallagher now claims that the song was not about Mathews at all, but he felt he had to go along with the rumour, saying "The meaning of that song was taken away from me by the media who jumped on it. How do you tell your missus it's not about her once she's read it is? It's a song about an imaginary friend who's gonna come and save you from yourself."
