They got into the groove in Holmfirth as part of the fight to stop Huddersfield losing its A&E department.
A spectacular night at the Picturedrome saw local bands strutting their stuff to raise cash to help with the campaign.
About 300 people were at the event which featured local performers and included a headline set from the Nu Popes, plus appearances from The Sellouts, The Dana Ali Band and 4Gotten Funk, along with the Honley Samba Band.
The event, on Easter Sunday, was organised by Sellouts bassist Ian Bagshaw.
He said: “I suppose I was behind it all, but really it organised itself because everyone wants to help with the campaign.

“I have known most of the musicians for a long time and the people at the Picturedrome wanted to help out as well – and with all their support it made it easy on my part.
“In Huddersfield we all seem to know each other by six degrees of separation and everyone knows someone who either works at the hospital or who has been treated there.
“It is so important to keep the A&E and because of that a real community spirit has grown.
“It was a tremendous night, the place was heaving and everyone seemed to enjoy it.”
During the show, organisers of the campaign to keep Huddersfield’s A&E, including Mike Forster, Nat Ratcliffe and Karl Deitch, went on stage.
Karl Deitch said: “It was a really good night. The place was absolutely rammed and everyone seemed to have a great time.”
The day before, Holmfirth had been the setting for a comedy gig in aid of the Hands Off HRI campaign.
The Laughing Gas Comedy Club hosted a fundraiser featuring 12 comedians at Brambles Bar and Cafe.
