Hmm... This has probably been brought to your attention before, but isn't the short drum intro to Blag also the same drum intro to The Night Comes Down? I was listening to Polar Bear in my iTunes library, and when it finished, it started playing what I thought was TNCD. But, it turned out to be Blag. Listen to the two introductions, and you'll see what I mean.
and the first notes of "she was once my friend" re-appear in "earth" ... so what? musicians often quote themselves. you will also find a part of the so-called guitar-extravaganza in "son and daughter" and even in "blag" ... (to be continued)
