Leaving on a Jet Plane

Remember that Peter, Paul, and Mary song, "I'm leaving on a jet plane," sing it with me now...

Anyway, I was watching the 25th reunion concert of Peter, Paul, and Mary on TV, and I was singing along with them.  Walter, who was in his crate sleeping, walked out to see what was going on.  I am not a good singer, and that is true.  But he didn't bite me to shut me up.  He just came up to me and leaned into me.  Then he went back into his crate.  I guess he was just wondering what that noise was that woke him up.....
