How to: annoy rock musicians

via Allmusic:  
Def Leppard’s [lead singer] Joe Elliott will release his own beer, which will be bottled by Dublin’s Porterhouse Brewing Company and served in their bars. Elliott said, “Over the years I’ve noticed a lot of musicians putting their names to a variety of wines etc which, as nice as a glass of red or white is, well, it’s not very rock and roll is it?!”  Source.
