Valentine rejoined the band to perform their first show together as a quintet in six years at New York's Bowery Ballroom on January 31, 2018, to announce the Broadway dates of their new musical, "Head Over Heels". The new musical—which premiered at New York's Hudson Theatre in the summer of 2018—features the band's hits (including "Get Up and Go" and "Lust to Love") as well as Carlisle's solo hits "Mad About You" and "Heaven Is a Place on Earth." The musical had a preview at the Oregon Shakespeare Festival in 2015.
