The song ‘Thank You’ was written by Richard Coulson for The Co-operative Bank and sung by a group of 50 Co-operative Bank employees from Manchester, Skelmersdale and Stockport.

The viral was created by Rapp Edinburgh.

The recording of the song and those singing has been released as a viral on You Tube and The Co-operative Bank’s Blog ‘Good With Money’.

Singers include Guy Herrington, director of marketing, Ryan Williams communication manager, Lynn Finney compliance, Rebecca Warner, claims advisor and Christopher Billett, customer service.

Guy Herrington, director of marketing for The Co-operative Bank, said: “We were really impressed with the positive response from our colleagues. The atmosphere during filming was amazing and we hope our customers have as much fun watching the video as we did filming it.”

He continued: “We are so proud that we have been recognised as the Best Financial Services Provider by Which? We decided that instead of sending a traditional ‘thank you’ note to every customer, we should do something a little bit more tongue-in-cheek and sing a song.

"We are not sure that we will be getting a call from Simon Cowell some day soon but as long as our customers are happy – that’s the most important thing.”
