The all-female collective, who are from the Derbyshire Dales, won the public vote with their 'Power Of Love' and 'Single Ladies' mash-up.
Judge Chucky Klapow claimed that Beyoncé should hire the group as her backing band, while Tamzin Outhwaite added: "You were all funky ladies tonight. Now, that was a show choir!"
Meanwhile, Bournemouth theatre school performers Swish took home the judges' wildcard following their rendition of 'Angels' and 'Let Me Entertain You'.
Swish edged out Essex's Original Talent in the sing-off, with the judges' vote split over who should go through. Duncan James and Anastacia backed Swish, while Chucky Klapow and Tamzin Outhwaite gave their votes to Original Talent.
Host Emma Bunton was forced to return to the public vote and revealed that Swish had received more support, meaning that they will perform in the wildcard show later in the series.
Don't Stop Believing continues next Sunday at 8pm on Five.
