The Attractions felt understandably insecure about their dispensability upon perceiving that their boss had cut a new album largely without them, and was planning to undertake a major tour showcasing the ''King of America'' material with his new musical partners. To allay their fears, Costello retooled his upcoming tour to allow for multiple nights in each city; playing one night with The Confederates (James Burton et al.), one night with The Attractions, and one night solo acoustic. In New York City he played five nights in a row! This arrangement put a strain on fans' stamina and wallets, as many wanted to see as many of the permutations available in their area as possible, not just one.

Later that year, he returned to the studio with the Attractions and recorded ''[[Blood and Chocolate]]'', which was lauded for a post-punk fervor not heard since 1978's ''[[This Year's Model]]''. It also marked the return of producer [[Nick Lowe]], who had produced Costello's first five albums. While ''[[Blood and Chocolate]]'' failed to chart a hit single of any significance, it did produce what has since become one of Costello's signature concert songs — "I Want You". It is on this album that Costello adopted the alias "[[Napoleon Dynamite]]", the name he later attributed to the character of the obnoxious [[emcee]] that he played during the [[vaudeville]]-style tour to support ''Blood and Chocolate''. (The pseudonym had previously been used in 1982, when the B-side single "Imperial Bedroom" was credited to "Napoleon Dynamite & The Royal Guard".)
In 1987, Costello, with a new contract with [[Warner Bros.]], began a long-running songwriting collaboration with [[Paul McCartney]]. They wrote a number of songs together, including Costello's "Veronica" and "Pads, Paws and Claws" from ''[[Spike]]'' (1989) and "So Like Candy" and "Playboy to a Man" from ''Mighty Like A Rose'' (1991) and McCartney's "My Brave Face", "Don't Be Careless Love", "That Day Is Done" and "You Want Her Too" from ''Flowers in the Dirt'' and "The Lovers That Never Were" and "Mistress and Maid" from ''Off The Ground''. In 1989, he appeared on the [[Home Box Office|HBO]] special ''[[Roy Orbison and Friends, A Black and White Night]]'', which featured his long-time idol [[Roy Orbison]], and was invited back to ''[[Saturday Night Live]]'' for the first time since 1977.
