Rolling Stones drummer Charlie Watts has described Mick Jagger's backside as "one of the finest views in the country."

Watts also revealed he does not own a mobile phone, and despite his love of horses, can not ride one.

Watts and the rest of the band revealed a few entertaining facts about each other during their first ever Twitter Q&A.

Keith Richards said the secret to immortality is to "go to church on a Sunday", while Ronnie Woods revealed he and Richards "are like book ends, we can live in a cupboard together if we had to."

The chat, hosted from their official Twitter account, saw them answering questions from fans using the hashtag #AskTheStones.

It was hosted by Edna Gundersen, a rock music writer and critic, and who used to be USA Today's pop music critic.

Watts kicked off proceedings answering a few questions and seemed bemused by the fact that the hashtag #CharliestoocoolforTwitter was trending within minutes.

When asked by @LPSmith24 is he has a favourite live album by the Stones, he replied: "Have I got one? No. I don't no, not really. I like other people's live albums, I never listen to my own things."

He laughed when asked by @leeknot "Are you sick of seeing Mick's arse after all these years?"

"No. (Laughs.) It's one of the finest views in the country."

Gundersen asked about his view from the stage, but he said he is often too busy playing to look at the view.

@Stonesdjenje asked him about loving horses, but wondered if he could ride one.

He revealed: "My wife is the one who has horse and I don't ride, no. Through her I am passionate about them, we have a lot we have about 300. So we don't have horses, we have herds of horses and they are very beautiful."

He also revealed that to this day he still gets butterflies before and when performing, saying: "Even if I played in a bar with two people at it, just sitting at the drums gives me butterflies."

Up next was Wood who looked back to joining the band.

@mickjagswag asked: "Did you know what you were getting yourself into when you joined the stones? #askthestones"

"Yeah I think I did. I bumped into a few, um, a few occasions Mick, Charlie and Keith (Richards), but, I more or less knew what I was getting into. When I made my first solo album in 1974, Keith came over for one evening and stayed for four months so I knew that was going to be the start of a good friendship. Mick came over and we actually prepared It's Only Rock 'n Roll there in my basement, in Richmond."

When asked by @SeamusMcRock if he had to share a room with another member of the band for one night, who would it be, he said: "That's not really a challenging question I've done that with everyone in the band. I used to do it all the time with Rod Stewart, we used to have some good times. But with this band, Keith and me we are like book ends and we can live in a cupboard together if we had to."

Jagger took the hot seat next and revealed the secret to keeping his voice so strong is karaoke.

He said: "Practise! You have to do it, you have to do warm ups and look after yourself. There's a regimen, you do a warm up before the show and before the tour starts I do a month of rehearsing. So every day I have to do a regimen and after a couple of weeks of that I do karaoke - solo karaoke, but not in a smoke-filled room."

Holding up a vinyl he revealed what fans can look forward to with the re-release of their classic album, Sticky Fingers. He revealed that among the many extras is a track with Eric Clapton playing Brown Sugar on someone's birthday.

Jagger reminisced about the late BB King and playing with him in Madison Square Gardens and a few years ago at The White House in the USA.

Jagger also gave a nod to Jay Z, listing him as one of his favourite rappers.

Talking about the Sticky Fingers album cover, which featured a real zip and was the brainchild of Andy Warhol, he revealed that to this day, they are still not sure whose jeans are depicted on the cover.

Last but not least Richards was up to answer questions.

When a fan asked him if he could teach him the secret to immortality, he replied: "I ain't there yet! So far so good. I think a clean and healthy life, plenty of exercise, go to church on a Sunday."

He said his advice to his 20-year old self would be to "get ready for a pretty fast ride."

Richards also remembered the late BB King, saying: "Sad loss, man. One of the greats, I mean, beautiful style and BB was a great guy. He was one of the true gentlemen and I shall miss him a lot. What can you say now, at least we have his records and farewell BB."
