Original Sugababes joined by old friends, new faces, and the stars of hit shows Wicked and Rent 20th Anniversary Concert .

Mutya Keisha Siobhan headline Sunday night's eclectic extravaganza of musical entertainment on the Main Arena stage at Manchester Pride, the UK's leading LGBT Pride event.

Anticipation for the group's new material has been rising since they announced their return in July 2012.

The girls, who release their new single 'Flatline' on September 1st, will next week play their first full headline show together in over 12 years together. Tickets sold out within 15 minutes of going on sale earlier this month.

Avant garde pop artist and friend of Manchester Pride Patrick Wolf returns to the Big Weekend for an exclusive acoustic set, Ren Harvieu follows up her spectacular performance at April's Supersonic charity dinner with an eagerly-awaited appearance, and BRIT award-winning musician Kate Nash makes her debut in the Main Arena.

Joining these exciting artists are up-and-coming rhythm and blues band The Quangos, retro vocal harmony group The Bobbysocks, electro-pop act Go Native, and singers Rebecca James and Matthew Wilson. The casts of touring shows Rent 20th Anniversary Concert and Wicked will also be performing a selection of songs from the hit musicals.

Chief Executive of fundraising charity Manchester Pride, John Stewart said "It's great to welcome new friends and familiar faces to the Main Arena stage for a day of fantastic entertainment. 

"We have a brilliantly varied programme for the Manchester Pride Big Weekend on Sunday.  From a reunited Mutya Keisha Siobhan headlining to smash show tunes from the casts of Wicked and Rent 20th Anniversary Concert, there really is something for everyone.

"With their new single due for release in September and album scheduled for early 2014, Mutya Keisha Siobhan are creating a huge buzz of anticipation.  The girls will go all out to ensure a memorable performance and bring Sunday's main stage to a storming close."

Advance Big Weekend  tickets are still available at a price of £21 from manchesterpride.com/tickets and selected outlets.
