Recuperation journey: Surprise compliment

When I was grocery shopping the other day my favorite George Harrison song, While My Guitar Gently Weeps, started to play. And I started to quietly sing along. 

I was startled when a young guy standing near me asked: "Are you singing?" 
I replied, "Yes, I'm old and this is a song from my childhood." 
He smiled and said he loved the song and I was doing a nice job singing it!

Whaaat??? I have a horrible singing voice. 

Maybe my kidney donor has a lovely singing voice? I must ask her.
