Rufus is a Tit Man, by Loudon Wainwright III, 1975.
A great, ebullient ode to breastfeeding, about Rufus Wainwright and his mom, Kate McGarrigle, by Rufus's father. I somehow had this album when it was new, and loved it. The irony that I love is that, despite being immortalized this way as a baby, Rufus grew up to be a famous non-tit man.
