Four names come to mind when you think of Motley Crue: Nikki Sixx, Tommy Lee, Vince Neil and Mick Mars. But the group underwent five lineup changes involving three other musicians at various stages of its 35-year career.

Granted, half of the band's six total lineups consisted of the twice-reunited famous original foursome, with Sixx and Mars always remaining on board. But the stories of how first singer Neil and then drummer Lee left and came back to the group -- and what happened while they were gone -- serve as great examples of the level of chaos that circled the band for much of its career.

After a fast march to the top and a decade-long reign as hard rock's most infamous bad boys, Motley Crue learned just how fickle mainstream music fans could be when they fired Neil and experimented with heavier and more serious-minded music on 1994's Motley Crue. Bringing him back but continuing to experiment with new sounds on 1997's Generation Swine didn't work much better.

So the band got back to basics on 2000's New Tattoo. Well, three of them, anyway. Lee decided he was sick of playing the same kind of music over and over, so he split. Then five years later they all realized once and for all that they were happier together.

That's the short version. You can read the complete history of Motley Crue's lineup changes -- including the three drummers that briefly filled in after various Lee injuries -- below.
