Steven Tyler on his Led Zeppelin Audition in 2008

Led Zeppelin famously reunited in 2007 for their now-iconic Celebration Day show. The show led to rumors the band was back together and would perform more shows. However, Robert Plant had no interest in such plans. This led to a number of singers "auditioning" to front Led Zeppelin for future performances. One of those singers was Steven Tyler.

Tyler talked about this moment in an interview with Classic Rock. The Aerosmith frontman explained, "I went over and played with Jimmy and the rest of them [in summer 2008.] It wasn’t an audition to be in Zeppelin, it was an audition to play with Zeppelin."

Tyler continued, "We were gonna do a couple of stadiums. And then while I was there, Jimmy spoke to me about maybe doing an album. I went home and thought about it for a couple days, and I got back to him and said: 'Look, Jimmy, you’re in an iconic band and so am I. I can’t, in good faith, leave my band and be in your band.'"

The Demon of Screamin' added, "We played all day for a week. Every time we took a break, I smoked a cigar and Jimmy smoked a cigarette. We went out back and I spoke with Jimmy about everything on the planet. it started out with: ‘Jimmy, you have no idea how grateful I am to have the chance to come over and jam with you guys.’ And he goes: ‘Well, maybe we can play some shows together.’ And I said: ‘Stop right there. I’m playing in a band with John Paul Jones?’"

Tyler concluded, "They let me sing every song I wanted – 'Black Dog,' 'Stairway To Heaven.' But it was just a week. And yeah, Jimmy asked me to do some stuff with him. But I didn’t want to be Coverdale/Page. Plus, I figured in the time it would take to do that, I could rally my own band together. So, was I gonna be in Jimmy’s band? No. But what an honor."

Classic Rock would note that Aerosmith guitarist Joe Perry said in 2010 that Tyler's audition didn't go over very well. Perry said at the time, "Page felt really awkward about the audition, but ultimately it was a group decision."

Of course, Zeppelin have yet to perform again together since 2007. The only "reunion" they had in recent years was in the court room when the band went through a lengthy trial over the copyrights related to "Stairway to Heaven."

Steven Tyler is many things: One of the greatest frontmen of all time, a poet and, it bears mentioning, one of the wackiest dudes to ever walk the Earth. All of that combined is what makes the Demon of Screamin' so iconic and so beloved.

With that in mind, it also makes the recent news of Aerosmith having to retire from touring all the more of a gut-punch.

On August 2, the band issued a statement announcing the cancelation of their farewell tour. The band issued the following statement:

"It was 1970 when a spark of inspiration became Aerosmith. Thanks to you, our Blue Army, that spark caught flame and has been burning for over five decades. Some of you have been with us since the beginning and all of you are the reason we made rock ‘n’ roll history. 

It has been the honor of our lives to have our music become part of yours.  In every club, on every massive tour and at moments grand and private you have given us a place in the soundtrack of your lives. 

We’ve always wanted to blow your mind when performing.  As you know, Steven’s voice is an instrument like no other.  He has spent months tirelessly working on getting his voice to where it was before his injury.  We’ve seen him struggling despite having the best medical team by his side. Sadly, it is clear, that a full recovery from his vocal injury is not possible. We have made a heartbreaking and difficult, but necessary, decision - as a band of brothers - to retire from the touring stage.

We are grateful beyond words for everyone who was pumped to get on the road with us one last time. Grateful to our expert crew, our incredible team and the thousands of talented people who’ve made our historic runs possible. A final thank you to you - the best fans on planet Earth.  Play our music loud, now and always.  Dream On. You’ve made our dreams come true."

It's devastating that Aerosmith won't be able to go out on their own terms. They more than deserved that after being active for over 50 years. While they may not have gotten the ending they wanted, there will always be the music. In the case of Tyler, there will also be his wacky one-liners. Here's a look back on ten quotes attributed to the Aerosmith frontman ranging from hilarious to poignant and everywhere in between.
