The band headline the event at Butlins Minehead, which takes place on November 25 to November 27. Also on the bill are Beardyman, Paul Heaton, The Whip, Jerry Dammers, Rob Da Bank, Andrew Weatherall, Don Letts and others.
Suggs told Digital Spy: "We've just got a lot of bands and DJs and films that have inspired us or hopefully will inspire us in the future. A mixture of old and new."
Asked which artists he had picked personally, he added: "I was very keen on Beardyman, The Cuban Brothers, who I think are great, the Gentleman's Dub Club and also Jerry Dammers and his orchestra are doing a little bit, which is great."

He added: "More and more I've enjoyed festivals. I didn't like them when I was a kid, I think obviously the facilities were a bit more sparse when I was younger, but now they're all great.
"There's so many great things live. There's been a demise of recorded music in terms of downloading, but I think that going to see a live band gets more and more exciting.
"Last time I went to Butlins was 1981 for an all-day soul weekender at Camber Sands. I love the idea of it. It's really a forerunner of what you now think of as a festival, where you play on the Friday and you get all sorts of stuff for the whole weekend."

"We're a pretty complex set of ideas," Suggs added. "There's seven of us and we all have our own thing and then the sum of the parts is what you see as Madness.
"Obviously we all have our own ideas about things. Something like this at Butlins, we can have a laugh and do serious things - and show films and music. It's a great outlet for showing a little bit of what influenced us and what makes us tick."
Asked if House of Fun Weekender artist Jerry Dammers will ever reunite with The Specials, Suggs said: "I have every optimism that he will. I see them all, not individually but on occasions and nobody seems completely intractable on that score.
"But of course it isn't our business and we certainly wouldn't take sides. But I would love to see them all back together, that's what I feel."
