Back when the Eagles were more than a cash register – with Randy Meisner on lead vocals and bass in 1977:
Glenn Frey revealed that the band were all on peyote when the pictures for their debut album cover were shot in Joshua Tree National Park. http://en.wikipedia.org/wiki/Eagles_(album)
They’ve always been a cash register, just back then they would at least put new products on the shelves. Meisner feared that last high note. Highly recommend streaming the two part “The History Of The Eagles” on Netflix.
