Making their third appearance in as many years, the band - which seems to have an untold number of members - have promised not to break the stage this year as they were famed for doing in 2011.
"It was Billy who broke it twice," says Rhys, "Hopefully, we're planning on not breaking it this year. We're hoping the OsFest guys have put some sort of provision in to stop that."
He continues: "This is the best festival in the British Isles, we're so excited and happy to be back.
"It's amazing this year performing alongside some big acts and we're pleased to be back."
Eggsy adds: "The band are really excited about watching the other bands, especially Hard Fi!"
But the guys are disappointed about one thing - missing Levi Roots yesterday: "If we're invited back again next year we will do a cooking demo and I bet it will be hotter than Levi's," says Rhys.
The lads say they love returning to Oswestry, with Rhys describing The Ironworks as "an awesome place", adding: "The people are really nice."
"It's a good part of the world," says Eggsy, "It's quite and nice - not violent like some of the places we visit!"
And the gang have been visiting a lot of places since we last saw them 12 months ago.
Maggot has filmed a part in a film due for release next year featuring Martin Freeman and Eggsy regularly appears on Welsh comedian Rhod Gilbert's radio show.
Graham explains: "We're all going to appear in a film Eggsy has written.
"But anyone in the band who does something else is supported - it's what we do."
Expanding on the project in question, Eggsy explains: "I've done a couple of films, one was just a short film that won a Reed Recruitment film award recently, but in this latest project I play a record producer who works with the Satan. We just need to get finance for it, but I'd like to start shooting next year."
He adds: "Working with Rhod has been great, I really enjoy it and he's a really cool guy.
"But I guess it's all just extra branches to the GLC tree!"
