Kiefer Sutherland says playing at Glastonbury was one of the ''greatest honours'' of his life.

The '24' actor performed a country music set at the festival on the Avalon Stage on Sunday (25.06.17) and he admits being on site at Worthy Farm in Somerset, South West England, was an unforgettable experience because Michael and Emily Eavis' event is unlike any other in the world.

Speaking to NME, he said: ''It's such an honour to have been invited, I can't even begin to say. This isn't just a British institution, it's a worldwide institution. This is one of the great festivals of the world, so to have been asked to play here is a little frightening, but also one of the greatest honours of my life. It's an afternoon that I won't forget. There's an energy here that's very special. I've never seen that at any other festival ... this festival has left a greater impression [on me] than any other before.''

Kiefer intends to come back to Glastonbury again in the future and experience the festival as a fan. This year a number of Hollywood stars were spotted partying on site including Brad Pitt, Bradley Cooper, Sienna Miller and Johnny Depp - who was well as performing also enjoyed a booze-fuelled reunion with his old friend Liam Gallagher, who performed on The Other Stage on Saturday (24.06.17).

And the 'Flatliners' star made up his mind to return after talking to one reveller who had injured herself in unusual circumstances.

He said: ''I met a woman out there who broke her rib, and I asked her how she did it and she said, 'Oh, I was riding a horse and fell off.' I was like, 'Holy shit, you can have horses here?!' That's what I'm gonna do - get a tepee and a horse and come back and hang out for a couple of days.''

Kiefer is a talented rider and has competed on the rodeo circuit in the US in the mid-90s after discovering his passion for the sport when he made 1994 movie 'The Cowboy Way.

Speaking about his days showing off his rope and riding skills, he previously said: ''One of the things I use to do a lot to relax was rodeo. I use to do team roping. I rodeoed with the US team champions - and I went to their finals in 1994 and 1996. I did most of my stuff out west. I would run a circuit from middle of Texas from far east [and] I would go all the way to California.''
