UPDATED 5/30/23: Bob Rock has issued a statement clarifying his comments about Nikki Sixx’s bass contributions on the first four Mötley Crüe albums, saying his comments were misconstrued and “at no time did I ever actually think Nikki didn’t play bass on Mötley Crüe’s records.” He also notes, “Nikki Sixx is one of the most talented players, lyricists and songwriters I’ve ever had the pleasure of working with.” 

In a recent interview, Bob Rock recalls a conversation in which Mötley Crüe bassist Nikki Sixx allegedly told him he suspected someone had replaced his parts on the band’s first four albums, including Shout at the Devil and Girls, Girls, Girls.
