Hey Sammy sued Dave when he heard 'Can't get the stuff no more', claiming he stole his chorus melody, right?
Dave could have easily sued the shit outta Sammy when he stole the chrous melody from 'Dance the Night Away' and used it (very badly) on 'Top of the World'. Shows what a fucking hypocrite Sammy is...
Just a little thought!
Or maybe Dave hasn't wasted his time listening to such rubbish, hence why he hasnt sued that fat fuck.
