This was the spectacle greeting Stourbridge shoppers as the Fizzogs teamed up with local band Empty Can to get people to donate to Children In Need.
The group, made up of Deb Nicholls, Sue Hawkins, Emma Rollason and Jackie Fellows, shot to fame earlier this year when their dance routine at the Stourbridge Festival went viral.
Deb, from Wollaston, said: "We have done lots of work with The Empty Can before so we thought why not get together and do something for this.
"We were going to do our usual flash-mob but then we thought 'well why don't we be a bit more original?'
"In actual fact it was a lady outside of the group who had the idea as with the amount of different things we do throughout the year we sometimes miss the bigger events."
The grannies performed to live music and people were asked to donate in return for the smooth moves.
Pudsey the Bear also featured alongside the act.
Miss Nicholls said: "We actually convinced local artist Luke Perry to be Pudsey. We have worked with him before so we asked him if he wanted to be Pudsey and eventually we were able to talk him round to the idea.
"When you are doing an event for Children in Need you can call the BBC and tell them and they will provide a Pudsey timeslot where they will give you the suit.
"When you are done with it you give it back and they hand it out to somebody else. Luke got a bit sweaty so I hope they had it dry cleaned after."
Miss Nicholls said she has no idea how much the performance raised as they collected the money in special collection tubs which they gave straight to the BBC once the performance was over.
"Even if we raised £100 just by doing what we were doing then I will be happy," Miss Nicholls said.
