Apparently Mick Jagger expressed interest in the lead role of Frank in the movie version of The Rocky Horror Picture Show, but Tim Curry got it instead.
My first thought on learning of this was, Well, if that had happened, we wouldn’t have been able to understand the lyrics. Seriously, I think Mick has a little contest with himself to see how unintelligible he can make his words every time he sings them. In a musical where the songs form an integral part of the plot, characters, and story, I shudder to think what he’d do to…oh, pretty much any of the words.
My second thought was a question. Why would the head of the [arguable, self-billed] World’s Greatest Rock ‘n’ Roll Band be interesting in taking time out from his busy schedule of writing songs, subsequently mangling the lyrics in concert, wielding his pelvic in a manner specifically calculated to freak out the straights, and rolling in dough to star in a cheap pastiche of B movie horror?
I’ve found two related answers. First, Mick has a side interest in acting, the same way David Bowie did. The role of Frank, with its hammy lasciviousness, fits in with Mick’s performing persona, so it’s a good match there too.
Second, I guess the Rolling Stones’ popularity waned in the early and mid 1970s. Though they remained popular with listeners, they didn’t sell as well as they had in the later 1960s. The rock establishment tended to regard them as irrelevant sell-outs.
In this context, Mick’s interest in Rocky Horror makes a little more sense. Contrary to my assumption, I guess he wasn’t busy being a superstar — or at least he had more free time around 1974 than he did about ten years earlier, when I Can’t Get No Satisfaction came out. The Stones’ comparative lull of the mid 1970s gave Mick time in which to entertain alternatives, including cut-rate, campy movies based on successful stage shows.
