Shel Silverstein: You're Always Welcome At Our House
On a side note, it's probably worth noting that Shel Silverstein - while best known as an author of children's books - had a fairly long and successful run as a cartoonist for Playboy Magazine. When I first discovered his music (and just what sort of music he wrote) I was pleasantly startled. With titles like "Stacy Brown Got Two" and "I saw Polly in a Porny", it's... not children's music.
