Off The Ground also featured collaborations with Elvis Costello on the tracks Mistress and Maid and The Lovers That Never Were. In fact, all the lyrics were given a thorough test, as Paul recalled at the time. "When I came to do this album one of the things I thought was that it might be good to be a little less casual and make sure I'd done my homework, make sure I liked all of the words in the songs. So I got a friend of mine, a poet called Adrian Mitchell, to look through the lyrics as if he was an English teacher. I went through it all with him and I can now say that they're poet-proof."
