D.P.
We have two signing videos - Talking Hands, and "Signing Time". I personally love the Signing Time series - the woman who leads (Rachel) is the mom of the hearing-impaired child (Leah) who is another main character. We bought the series of the first 3 DVDs and it came with a CD of the songs on those DVDs. My kiddo has a speech delay and we used signs before he started to make progress, and he can sing every song on the CD (and he'll sign along to some of the songs, too!)
