One Direction may be down a member, but if need be, the guys have a replacement.

The lads of 1D visited Capital FM during their Summertime Ball earlier this month, where the DJs put them through a one-minute round of superlative questions ("Who stinks up the tour bus?" "Who is likely to use up all his money in 20 years?"). They also asked the boys who they would choose to fill Zayn Malik's shoes, since he left the band in March.

Harry Styles had the perfect response: "My granddad suggested that he join. He's 80."

What would it be like to have Grandpa Styles on tour? The guys just had shrugs all around.

I guess we'll just have to find out, no?
