Obsesseive collector Matt Wells is king of both the Underworld and the Dark Side.

Matt, 31, has spent about £5,000 building up an exhaustive treasure trove of memorabilia devoted to the dance band Underworld.

His home in Mile Oak is also decorated with a display of 1,000 Star Wars figures.

The mania for collecting runs in the family.

His mother used to hoard Claris Cliff plates and ornaments while his wife has a cabinet full of Beanie bears and books by the cartoonist Giles.

Marketing analyst Matt said: "I probably get it from my mum. Neither of us likes throwing anything away - I always worry something might turn out to be collectable."

Matt started collecting Underworld records in 1992, while at Manchester University.

Since then he has tried to snap up every T-shirt, remix, promo and limited-edition release by the band, whose biggest hit was Born Slippy in 1996.

His prize possession is a one-off unreleased acetate of remixed track Confusion The Waitress, worth at least £250.

He scours the internet for Underworld oddities too, including band-related phonecards released in Belgium and US publicity packs.

His estimated 500 Underworld goodies are stored separately from his other 10,000 records.

He said: "I try to listen to Underworld every day. I love their music and thought 'I'm going to collect as much as I can'.

"That means while most people are happy to buy a single or album once, I have to buy every format of everything even if I have the tracks already.

"If they re-release something in a different sleeve, that's a different record to me."

Matt said he had no great desire to meet the band, though he has had email correspondence from former member Darren Emerson.

He said: "I'm not interested in stalking them or anything like that.

"They're just guys who make music which I like listening to."

His Star Wars figures are all displayed in their original boxes, lined along the walls of his study.

But he said: "You can never complete a Star Wars collection because there is so much out there.

"I am trying to cut back a bit now my baby daughter Isabelle has just been born."
