In the Captain and Tennille song "Love Will keep Us Together" I heard:
When those girls start hanging around talking me down
Hear with your heart and your long hair astounding....
instead of : Hear with your heart and you won't hear a sound
and
Young and beautiful
Someday your look so evolved
rather than:
Young and beautiful
Someday your looks will be gone
A childhood belief about misheard lyrics

- When I was five or six, I was worried that I'd lost my heart because I didn't hear it beating.Anon
- The song called heart of glass mixed me up as a kid. I heard "Heart and ass". — oops
- I always hear Manic Street Preachers 'You Love Us' as 'You Love Arse'.— Lou
- I used to believe that only people that were in love had a heart.— Nikki
- I used to think that when people had heart attacks someone came and stabbed their heartAnon
- I used to think you could have a heart attack if you fell in love too deeply!Anon
