Queen’s subsequent album was Innuendo, on which May’s contributions increased, although more in arrangements than actual writing in most cases; for the title track he did some of the arrangement for the heavy solo, then he added vocal harmonies to “I’m Going Slightly Mad” and composed the solo of “These Are the Days of Our Lives”, a song for which the four of them decided the keyboard parts together. He changed the tempo and key of Mercury’s song “The Hitman” and took it under his wing, even singing guide vocal in the demo. May also co-wrote some of the guitar lines in “Bijou”.
