Jack Johnson, Henry Wright and Adrian Brakewell found fame across the city last month after they started entertaining locked-down residents with their bin round moves.
But now the trio have taken it a step further and gone global, with their performance of You're The One That I Want viewed more than 2 million times on Facebook.

In the clip filmed this week Henry dons a blonde wig to play Sandy, while Jack Johnson plays Danny and Adrian joins in with the dancing.
Jack, 36 and from The Scotlands in Wolverhampton, uploaded it to Facebook and it's now been watched more than 2.3 million times.
He said: "We are just trying to cheer people up during the coronavirus outbreak. That's what it is all about it.
"The messages we have received from people have been inspiring, saying 'you made us so proud [of being from Wolverhampton] and you have cheered us up'.
"They have been asking us for more and more. This video has actually gone worldwide. We have had messages from lots of people."
He added: "We have had been thinking about doing Grease for a while.
However they are not just aiming to make people laugh - there is a serious cause which is raising money for Compton Care in the process.
Jack has been sharing links to his fundraising page and so far has raised more than £1,500 for the Wolverhampton hospice.
The charity provides care to people with complex and incurable conditions.
Jack started sharing videos of the crew dancing to TikTok favourite Blinding Lights by The Weeknd during their rounds across the Penn and Bradmore areas last month.
And the lads' not-quite-professional-level dancing and camaraderie has gone down a treat.
"We all get on fantastic," said Jack. "It's all about having fun."
