Very powerful song, I remember it as a child.

Another song also about Clapton's son is the Genesis song "Since I Lost You" from the album "We Can't Dance". They played it for Clapton and he really appreciated it according to Phil Collins' autobiography.

"And my heart is broken in pieces"

I find that with "Tears In Heaven" there's a lot in common with the song "Imagine" by John Lennon in terms of how it makes me feel.
