I was going to make this a Saturday song, but it's as much about the poem as the music. (The song is Towerblock by Julia Fordham.)
The poem is by Marianne Wade, who lost her mother (in awful stages, I imagine) to Alzheimer's, but it pertains to anyone who has ever lost a person they loved, whether they died or just went away. A beautiful song, a meaningful poem, a lovely video.
Deep thanks to Marianne for allowing me to embed this...she had embedding turned off and changed that just for me.
