Mötley Crüe call it quits, Bieber not in trouble Iconic heavy metal band Mötley Crüe have announced they are hanging up their guitars for good after three decades. Band members even signed a contract that will permanently dissolve the legendary rock group after one final tour - which will last two years and feature 72 concerts. It is their second farewell tour in less than a decade, but the rockers vowed that this time, they really are calling it quits. Tommy (Lee) said it best recently when he said a farewell tour is when a band does a farewell tour and then gets back together and does another farewell tour and then breaks up and gets back together until there's no milk left in the titty, and it's a rip-off to the fans. And so we decided to call this a final tour and sign a contract telling you that this is real," said Mötley Crüe band member, Nikki Sixx. When the four of us are on stage together, it's special. That's going to be the worst part is just knowing I'm not going to be on that stage with the guys again," said Mötley Crüe band member, Vince Neil. However, the live gigs will be used to promote a film adaptation of the bestselling Mötley Crüe bandography "The Dirt," due out next year, as well as a country-music tribute album, scheduled for this summer. Founded in California in 1981, Mötley Crüe has been described as the world's most notorious rock bands. It is without doubt one of the most successful bands of all time, with more than 100 million albums sold worldwide.
