That's right, I just discovered that maybe she started to do it in the "Rumours tour". I'm not sure if it happened from the first concert (February 24, 1977 at the Nassau Coliseum, Uniondale, NY), but in the video of the japanese concert at Budokan, Tokyo (1977-05-12) she did it and from that moment on we know she sang "Songbird" at the end of every concert (since in 1975 they ended with "Hypnotized")
