Now this is interesting. After the announcement that Aerosmith frontman Steven Tyler would be leaving the legendary classic rock group, Tyler checked into rehab for treatment of his addiction to painkillers. But this is obviously one of those rehab clinics that's a little loosey-goosey about security, because Rolling Stone is reporting that Tyler commandeered the PA system of a Rancho Mirage, CA Home Depot store to sing "Dude Looks Like A Lady" to the perplexed drywall purchasers before taking a hit off of a helium tank and continuing in full Chipmunk voice. This actually follows a prior karaoke performance by Tyler at a Palm Springs bar where he grabbed the mic from two yutzes butchering "Don't Wanna Miss A Thing." Where will the phantom Karaoker strike next? Look for the tell-tale sign of scarves wrapped around the microphone.
