Scramble up a ramp just right of the start of "Where Eagles Dare" until you reach a crack system beginning over a roof. The rock is a little chossy here but greatly improves once you pull over the roof and start angling up the crack. After about twenty-five feet of crack climbing comparable in steepness and difficulty to that on "Illusion Dweller," you reach a 'V' in the crack system. The original line takes the right crack and makes a long traverse to the same belay as for "Desert Song." Another option is to take the left crack straight up to a ledge, traverse right about six feet to a bolt, and make one or two face moves (.10a) in order to reach a set of anchors on "Where Eagles Dare."
A decent alternative to "Illusion Dweller" if that route is busy.
