From Wiki:
On March 26, 2008, several news outlets reported that Dr Pepper will offer a free can of soda to everyone in America - except the band's former guitarists Slash and Buckethead - if the band releases Chinese Democracy this year.[34] In a posting on Guns N' Roses' official site, Rose responded, "We are surprised and very happy to have the support of Dr Pepper with our album 'Chinese Democracy,' as for us, this came totally out of the blue. If there is any involvement with this promotion by our record company or others, we are unaware of such at this time. And as some of Buckethead's performances are on our album, I'll share my Dr Pepper with him."[35]
