I'm pretty sure the only song Alex has written lyrics on is Chemistry, (and possibly In The End) “Lessons” is an interesting song because you wrote the lyrics. How did that come about? We just thought it would be kind of cool if Ged and I wrote lyrics for at least one song. He wrote “Tears.” That was really the reason. I can’t say that I’m comfortable writing lyrics. Even later on with my solo record, Victor, it was the hardest part. It doesn’t flow for me the way I would like it to. And I’m not sure that would be different if I did it more often. You know, Ged’s “Tears” is so typical of the kind of stuff that he likes to write and do, even today. He likes those more ballad-y pieces that are emotive and sweet. I’m the dirty, heavy guy [laughs]. http://www.rollingstone.com/music/music-news/rushs-alex-lifeson-on-40-years-of-2112-it-was-our-protest-album-177351/ I dont recall him writing chemistry? check rush.com Either that article is fake, or their own website is wrong
