Liam Payne finds it tough to "remember" One Direction's lyrics.
He admits he finds it tough to recall his band's lyrics as there is "a lot of stuff to remember" from that time.
And the 26-year-old singer also confessed he doesn't remember what songs he sang on the 'X Factor' with his bandmates - Niall Horan, Harry Styles, Louis Tomlinson and Zayn Malik.
And Liam still finds the band's meteorological rise to fame as "insane".
And Liam previously said that if the band decide to reunite in the future, it would be likely they'd all perform one another's solo songs.
