The point of this game is to quote a line (or two) from a Genesis song that begins with the last letter from the immediate previous poster.
"I'm on my guard with all the exits sealed" (from "No Reply At All" - you don't need to give the origin unless you want to)
can have a reply like
"Demi-god and nymph are now made one" (from "The Fountain Of Salmacis")
If a line ends with "e", and you don't want to use "e", try to use the letter before the "e" (since it is the most common vowel) - e.g., "No time for romantic escape" (from "Back in N.Y.C.") for the previous line - otherwise, treat the "e" as a wild card and use any line you wish to continue.
"Can you tell me where my country lies"
