What's the intention of "(What's So Funny 'Bout) Peace, Love And Understanding"?

Maybe that differed between the UK and American editions.

I guess you’re right. I was only familiar with the American version of the album. Wikipedia says

The American release omitted “Sunday’s Best” and added Costello’s cover of Lowe’s “(What’s So Funny 'Bout) Peace, Love, and Understanding” as the side two closer.[41][49] Following the 1993 reissue, “(What’s So Funny 'Bout) Peace, Love, and Understanding” was added as the album’s final track.[14][22]
