He didn't say much new,

Dave will open first show, they will alternate after that.

Sammy almost called it off becuase he did not want to open any show, but he said he dropped the ego thing because he realized they both share fans and its all about rock music.

He did say he thinks Dave will end the tour with his head between his legs from being blown off stage every night, but he said it all in fun banter as if he knows Dave is thinking the same thing.
