I agree, I've never seen him be anything but pleasant to his fans! It does seem an odd detail to throw into a review.
I go back and forth, trying to decide whether this or O Lucky Man! is my favorite AP album. I really love the autobiographical parts of Between Today and Yesterday, and for a year or so of my life I listened to this album two or three times a day. (You see, Daria, you're not the only one!

)
It coincides with my favorite era in literature, which was the mid-1950s through 1960s British novels/plays/movies, about the upheaval of the class system after World War II. The gritty images of the workers rising at dawn to go off to the mines (or shipyards, or factories), the camaraderie of the pub, the loner striking out to find fame in the big modern city, really resonate with me.
Perhaps my favorite songs are "Away, Away" (so haunting), the rowdy singalong of "In Times Like These," the poignance of "City Lights" (I think of this as the continuation of "Arrival" from O Lucky Man!), and that powerful blues ballad, "You're Telling Me." I often give just these 4 tracks to people I am trying to turn on to Alan Price. They really show off the breadth of his musical range, his great ear for melody, his fantastic singing, and of course his keyboard genius.
And that's not even mentioning "Jarrow Song," which is definitely one of Alan's greatest tracks ever!
PS "Dream of Delight" strikes me as a slightly silly song, but I can't help loving it. There's a husky rasp to Alan's voice there that is soooooo thrilling!!
