I just added "Pete Seeger at 89" to my CD collection. It is a huge collection of cuts from this legendary figure in folk music.
One that I think might become my favorite is his song about babies growing to adulthood and the melancholy caused for parents by that growth. It is what we hope will happen to our children - if we're functional parents, but it is also painful to see. We may battle with our children when they're little, but we remember those days with great fondness. The memory of the battles fade, even become funny, while the memory of the waddling little baby just learning to walk, with a whole world of possibilities ahead, remains as vivid as any memory we have.
For those who've never heard Pete Seeger, here's a Youtube video from his younger days.
