Once known for his frequent drug intake, Liam Gallagher has revealed his band's new album was written with a "clear head".
Formally the Oasis frontman, the singer said his group Beady Eye had a "new-found focus", suggesting he had moved on from his excesses.
Gallagher, 40, said: "We had a new-found focus when we were writing it - we really got our heads down and got our s*** together - clear heads, none of that c*** from the 90s."
Gallagher's brother Noel walked out on Oasis in August 2009, following a cancelled performance at V Festival.
The group have even used iPhone apps to work on some of the songs for their forthcoming album BE, out on June 10.
