In the case of Def Leppard, now celebrating forty-five years since the Sheffield, England band's introductory "On Through the Night" was released in March 1980, anyone wishing to understand where they come from musically would do well to listen here to my guests Def Leppard lead singer Joe Elliott and lead guitarist Phil Collen. The tunestack on "Yeah!" is a virtual look at the playlists of BBC Radio One and Radio Luxembourg circa 1973.

Chris Cornell's voice singing "Like Suicide", framed only by a twelve string guitar, makes it seem like only yesterday instead of three decades ago that Soundgarden led us all into the "Superunknown".

The third Steely Dan album,"Pretzel Logic" in February 1974, has always served as a distinct demarcation line in the evolution of the eclectic band led by my guests, songwriting duo Donald Fagen and Walter Becker. "Pretzel Logic" by Steely Dan is significant because it contained the #4 Billboard hit, "Rikki Don't Lose That Number", with the album Top Ten in sales as well. Rolling Stone magazine ranks "Pretzel Logic" at #386 on their Top 500 Albums of All Time.
