ACTS from the 60s, 70s, 80s and 90s will play on a second stage at this year's Manx Telecom Bay Festival.
The festival site at Noble's Park, Douglas, will be divided into two parks - the North Park with the big Valhalla blackout tent where the festival headliners will play, plus the South Park with a huge outdoor covered stage.
On the South Park stage acts will include FIVE, 911, S Club, 10cc, Go West, Gerry and the Pacemakers and Les McKeown's Bay City Rollers.
The festival takes place from Friday, June 17 to Sunday, June 19.
Festival co-promoter Jamie Irving said: "We are trying to make this festival something for everyone and for all budgets and I think with these improvements on 2010 we are delivering exactly that.
"We are extremely pleased to announce that on the South Park stage we will commence each evening session with the first three hours being devoted to 'Four Decades of Pop'.
"On the Friday night that will comprise of FIVE, 911 and headlining will be S Club singing all their number one hits including Reach (For The Stars), Don't Stop Movin' and Never Had A Dream Come True.
"All these groups admirably cover the 90s. On Saturday we have the 70s and 80s covered with the iconic masters 10cc, performing their hits of I'm Not In Love, Wall Street Shuffle and Rubber Bullets and Go West singing their hits including Call Me and We Close Our Eyes.
"The 60s and 70s are very well represented on Sunday by Gerry and the Pacemakers signing their number ones, I Like It, Ferry Cross The Mersey, How Do You Do It and the legendary and immortal You'll Never Walk Alone!
"Les McKeown's Bay City Rollers were nothing short of phenomenal in the early 1970s with a succession of number one hits and teen mass hysteria that followed them everywhere.
"This whole spread of 'Four Decades of Pop' promises to bring nostalgia flooding back with the audience singing themselves hoarse along with all these iconic and totally legendary artists."
Meanwhile the final line up for the Comedy In The Park event, which takes place on the Friday, has also been revealed.
It will feature Alan Carr, Dara O'Briain, Kevin Bridges, Shappi Khorsandi and Andy Parsons.
