The "Musicians Who Turn 50", "Musicians Who Turn 60", "Favorite Drummer" and "Favorite Guitarist" were such hit threads on FR, I've decided to do this one. Who is your favorite SONGWRITING DUO? We all know that Lennon-McCartney were amazing together and possibly the best songwriting duo ever. They might be mentioned several times on this thread. If you choose John & Paul, be specific about which song and lyric(s).
