Leppard are re-recording as much of their back catalogue as possible after failing to reach an agreement with Universal over digital releases. And last month the band cut five acoustic songs performed during their Rock Of Ages tour for a medley released to iTunes.

"We're trying to wrestle back our career and ownership of these songs," said Elliott in an interview in the latest issue of Classic Rock. "They [Universal] own the originals, we're at loggerheads with them over the digital rights. And as long as they're playing silly buggers we'll just keep recording them again."
