In the meantime, I've been spending time looking for new songs to sing to Katie. In the last couple of days, I've tried Daisy Jane, Sister Golden Hair, Eli's Coming (not too popular), Old Fashioned Love Song (better!), Marrakesh Express, Teach Your Children, and Bad, Bad Leroy Brown, along with some others that have just slipped my mind right now.
I'll just keep working on this.
