VOCAL harmony trio The Puppini Sisters have been un-veiled as the headline act at Hartlepool's retro celebration The Diamond Festival this summer.

The girls will be among a host of top-quality acts ap-pearing in the entertainment marquee in front of Hartle-pool's Maritime Experience on Saturday, June 2.
