Watch The Wanted play acoustic songs
The chart-topping band played acoustic versions of their hit single Glad You Came and the Goo Goo Dolls' classic song Iris.
The Wanted recently conquered the US singles chart with Glad You Came, so they decided to break out the guitars and record a special session at Slacker Studios in San Diego.
Glad You Came reached number three on the Billboard Hot 100 Chart last month, while the Goo Goo Dolls' Iris was first released in 1998. The Wanted definitely make the cover their own though with some beautiful harmonies.
Watch the breathtaking renditions below:

The star headed straight from the jungle to panto...but clearly hadn't had time to learn her lines!
