It's no secret that Alter Bridge frontman Myles Kennedy was among the singers auditioned by Jimmy Page, John Paul Jones and Jason Bonham back in 2008 when the three were considering touring together without Robert Plant.
Kennedy has spoken openly about the audition over the years, but only recently has he revealed the name of one of the 'new' songs his potential bandmates showed him.
The singer told Eddie Trunk in a recent interview that the riff they jammed on was called "Embyro No. 1."
"Jimmy was playing something and I think that's what we were jamming on," Kennedy said. "I remember that riff in my head. It was a really cool riff."
Kennedy said they jammed on the new idea at the end of their session. Previous to that, they performed "No Quarter" and "Kashmir," among other Led Zeppelin tunes.
You can listen to a rough recording of "Embryo No. 1" below.
Page revealed parts of "Embryo No. 1" and another idea called "Embryo No. 2" in the 2008 guitar documentary It Might Get Loud.
Coverdale went on to suggest Page team up with singers from the rock and pop world (Carlos Santana-style) and release some new songs.
