Legendary Manchester DJ Graeme Park will spin an all day, 12-HOUR set on Saturday.
The Hacienda favourite's marathon set is due to start at 12 noon and will run through to midnight.
Park said he would be 'digging deep and playing an eclectic selection of grooves'.
"Come on then!" he wrote on Twitter.
The set is for Manchester's virtual nightlife platform United We Stream.
The streaming channel was launched by night time economy adviser Sacha Lord and the Greater Manchester Combined Authority to support the region's restaurants, bars, music venues and other cultural establishments that have been hit the lockdown.
More than £382,242 has been raised since April 3.
Charities supporting those most in need have also benefited.
More than 14 million people from as far away as California have tuned in to streams including an all-day Hacienda house party, which also featured Park alongside American house legends David Morales, Roger Sanchez and Todd Terry.
A Spike Island-inspired show from Paul Oakenfold and a DJ set from Maxine Peake have also been highlights, alongside a mini Moovin festival and cookery demonstrations by chefs Gary Usher and Simon Wood.
A wide variety of music and art is being showcased.
News of Park's set was confirmed tonight by Parklife and Warehouse Project founder Lord.
Sacha said on Twitter: I can't quite believe this.
"This Saturday on UnitedWeStream.co.uk, for the first time ever, Graeme Park will be doing an all day 12 hour marathon set.
"All day long and into the night."
"Saturday sorted,2" said one fan on Twitter.
Another added: "Massive respect for this. I'll definitely be there."
Donations can be made via UnitedWeStream.co.uk or text MUSIC to 70660 to donate £5.
