Dame Shirley Bassey, Elvis Costello & The Imposters and Will Young will perform at Henley Festival 2016.
Dame Shirley Bassey and BLAKE
The news follows the announcement that Sir Elton John will open the music extravaganza by performing on the event's floating stage on July 6.
Bassey will be teaming up with Brit Award-winning vocal group BLAKE on Saturday July 9 and music legend Elvis Costello & The Imposters will provide the entertainment on July 7.
The following night sees classical Welsh Opera singer Bryn Terfel performing with the Welsh National Opera Orchestra.
And closing the week of world class entertainment is pop singer Will Young who will bring the festivities to a close on July 10.
The 'Leave Right Now' hitmaker can't wait to headline the festival and is thrilled he has top billing on one of the nights just like his hero Elton.
Of his closing slot, he said: "I'm really very excited to be closing Henley Festival on the Sunday night. I had such fun playing there last time, it's such a beautiful setting on the banks of the river Thames, not to mention headlining alongside one of my favourite people, Sir Elton John."
One further headliner is to be announced for Saturday July 9.
Tickets go on sale on February 25 at 10am.
