I've noticed recently that the Wikipedia articles for the albums from TRESPASS thru THE LAMB LIES DOWN ON BROADWAY are naming the "actual writers" of all the songs, with lyrics and music listed separately. The citation given for all this information is "Genesis 1967 to 1975 - The Peter Gabriel Years" by Mario Giammetti.
For the most part, my reaction to these is "Yeah, I knew that" or "Uh-huh, OK, I can see that." In some cases it's "Really??" or "Hmm, something seems to be missing."
Does anyone have any thoughts about this information? If it's accurate, then the only individual credits we're missing from the Gabriel era are the pre-TRESPASS tracks, "Happy The Man" and "Twilight Alehouse" (although I'd bet the official Banks-Gabriel-Phillips-Rutherford credit on that one is accurate).
