Final 'Ace of Cakes' episode advert song?

There is currently an advert being shown on UK TV for the last episode of 'Ace of Cakes' on Watch. It sounds like a country song and the only lyrics shown in the advert are "what a way to go, what a way to go". I have tried googling these lyrics and all that is coming up is 'What a way to go' by Ray Kennedy. If anyone knows what this song is called please tell me. Thanks in advance.
