Liam Gallagher says Oasis should never have split up - and that he's ready to get back together whenever Noel is.

The brothers are the focus of a new documentary film about the band. Supersonic uses archive footage and interviews to tell the story of their rise to fame.

Liam says he was impressed the film-makers managed to find so much material from when the band were at their peak.

Speaking ahead of the release, he said: "[It] brought back memories, some good, some bad. But, overall I think, the majority of it is pretty euphoric so i'm quite happy with it."
