With his ([article id="1626862"]apparently former[/article]) band in a state of flux and his mates embarking on a rather open-ended search to replace him, [artist id="1204674"]Steven Tyler[/artist] spent the weekend doing what many Americans do: making a quick trip to the Home Depot.

However, unlike many Americans, Tyler also took the opportunity to serenade shoppers with a medley of [artist id="1028"]Aerosmith[/artist]'s greatest hits. For real.

That's according to TMZ, which reported Tuesday (January 26) that Tyler gave an impromptu concert to customers at a Rancho Mirage, California, Home Depot, grabbing a microphone and singing snippets of "Dude Looks Like a Lady" and "I Don't Want to Miss a Thing" over the store's intercom system.

The site quotes "multiple employees" as saying that not only did Tyler belt out the tunes, but he also signed autographs for fans and at one point took a hit from the store's helium machine and kept right on singing, albeit in a slightly higher register.

An e-mail to Aerosmith's management seeking comment on the situation was not returned by press time.

While Tyler -- who, in late December, [article id="1628759"]checked himself into a rehab facility[/article] to treat an addiction to painkillers -- was busy singing, his Aerosmith bandmates were busy shopping ... for a new frontman. In a recent interview with The Toronto Sun, guitarist Joe Perry said that while Tyler gets healthy (and has surgery on his leg and foot), the band is actively searching for his replacement.

"As far as I'm concerned, [Tyler] hasn't left the band. ... He hasn't talked to anybody in the band. ... It's kind of hard to get a straight answer about what's going on," Perry said. "So, in the meantime, the rest of the band wants to play. And I want to play with the other guys in Aerosmith. So the four of us are just making plans. We're gonna find somebody to get in there and fill [Tyler's] spot.

"The people we're talking about, as far as auditions go, we'll probably just sit around and have a couple of drinks and see if we get along. Because we're already gonna know that they can sing," Perry continued. "I can't say who we've been talking to. ... We have a few people we've talked to, and we'll see how it goes."

Perry added that the band fully intends to return to the road, with Tyler's replacement in tow, and the guys will definitely call themselves Aerosmith. But he didn't exactly close the book on Tyler's time in the band, either.

"I'm ready to write with him, to play onstage with him anytime he's physically ready and wants to do it. But it's really up to him. His doctor says he's gotta have surgery on his legs and his feet and he's gonna be out of the picture for a year," Perry said. "In that time, he should be able to come around. And the last things he said to the press were that he wanted to work with the band and sing with the band, so we'll see."
