Name your movie Jane Got a Gun, and you pretty much have to put Aerosmith's "Janie's Got a Gun" on the soundtrack. But what if it's a Western, and the hit doesn't fit? No problem — just hire Steven Tyler to record a new solo version.

Tyler talked about his contribution to the upcoming Natalie Portman project during a recent Rolling Stone interview, saying he delivered a "dark, smoky backroom rendition" of the song he originally recorded with the band for its 1989 Pump LP. It's all part of the run up to his first full-length solo effort, which he's been working on in Nashville while Aerosmith ponder their own future in the studio.

As previously reported, at least part of the band is hoping Tyler's solo effort could lead to more new music from Aerosmith, although they've publicly questioned whether there's a need for more albums following the somewhat disappointing response to 2012's Music From Another Dimension! Tyler was noncommittal on the subject when pressed by Rolling Stone, merely shrugging, "Aerosmith will probably do something again. I don't know for sure. I just know what I'm doing now."

In the meantime, there's another round of tour dates to get ready for, and Tyler also echoed guitarist Brad Whitford's recent prediction that they'll mix up the set list in 2015. "We're gonna do deep," Tyler concurred. "People want to hear 'Sweet Emotion,' 'Dream On' and 'I Don't Want to Miss a Thing' — all that over and over, and there are other songs of the cloth we were cut from. Being in a band for 40 years, what is the passion, the impetus? For me, it comes from rehearsing a few songs we used to play great and didn't give a s--- if other people cared about them."
