As a singer, I prefer PR to AL, he’s obviously one of the great blues/rock singers but therein, to me, lies the problem. Apart from a few songs (It’s Late etc), Queen weren’t particularly bluesy. I saw Queen with PR a few times and to me it just didn’t feel like Queen at all, apart from when Rog or Brian sang their stuff. I kind of begrudgingly saw them with AL at the Hammy Apollo on their first run of dates and I thought they were superb. Adam wasn’t the most dynamic or charismatic frontmen then, but he was right for the band and it felt much more like Queen again
