These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Face of the Band: David Byron was this for a long time until his departure (precipitated by his alcohol problems) was forced by Ken Hensley. Now it's probably Mick Box.
Germans Love David Hasselhoff: In their native UK (and America) they're essentially a cult band, but in Asia and mainland Europe (particularly Germany, entertainingly enough) they retain a strong following and continue to sell out arenas there.
Harsher in Hindsight: "Stealin'" contains this lyric: "All that fightin', killin', wine and those women, gonna put me to an early grave." Two of the performers on that song did meet early graves: bassist Gary Thain OD'd on heroin at 27, and singer David Byron died of "alcohol-related complications" at 38.
Vindicated by History: Their first album was met with poor reviews upon release, with one reviewer famously saying that she would kill herself if the band actually made it. The album is now considered a landmark in the history of rock and metal.
