Variations on the same theme

I don't understand, his new album is This Delicate Thing(...), and On the Verge(...) is only the title of the song isn't it ? I really am lost with all these songs and albums, he worked a lot during these years I wasn't listening to him ! On Amazon, they only have This Delicate Thing, for the other albums it's secondhand. So I think I'd like to buy this one on Amazon, and since I also need a book, I'll buy them together. But if you could find The Tension and the Spark for me, that would be cool. Because if I buy it on Amazon, I'll have to pay the shipping twice anyway. So if you find it for less than 15€, I'll be interested. Thanks !
