Feel free to say out loud -- "Well, I didn't see this one coming" -- but there's a ZZ Top musical in the works, according to Rolling Stone. The show, titled Sharp Dressed Man, is currently in development, and set to open in 2020. Bandmembers Billy Gibbons, Dusty Hill, and Frank Beard will serve as executive producers -- with "Las Vegas-based Caesars Entertainment, led by Michael Gruber and Jason Gastwirth developing the jukebox musical."

Rounding out the team is ZZ Top manager Carl Stubner who'll serve as producer, with the musical's book being written by Robert Cary and Jonathan Tolins, who are best known for the recent teleplay for Fox’s Grease Live!

According to the press release announcing the production, "Sharp Dressed Man is an outrageous, bawdy musical romp about a Lone Star auto mechanic who becomes a modern-day Robin Hood, stealing hearts -- and car parts -- with the help of his merry band of beer drinkers and hell raisers." No opening night or venue has been announced yet.

Guitarist Billy Gibbons told us that when writing their music, the members of ZZ Top have never forgotten where they came from musically: "Take, y'know, all the obvious influences -- all the blues, and we could name Muddy Waters, and Howlin' Wolf, and Jimmy Reed, and even Rolling Stones, Cream, that whole thing -- you put it all together, and you got a big handful of what we all love. 'Course, then we twisted it into something undefinable, but it still keeps us where we're real comfortable being."

ZZ Top will next perform on June 4th in Helsinki, Finland. The band will be on the road in North America starting in August playing both solo dates and with special guests, Cheap Trick.
