Rob,
I haven't found the "Heavy Horses" album memorable, apart from the 9-minute title track, but after discovering this glowing review today, I may revisit it:

"Stormwatch" is one of my favourite Tull albums, with its 10 tracks all strong and plenty of variety in the melodies and subject matter. The obvious standouts are "Dark Ages" and "Flying Dutchman", but I find the closing instrumental "Elegy" near-perfect. (I may ask for it to be played at my funeral, along with Gord's "Carefree Highway" and James Taylor's "You Can Close Your Eyes".)
