Rememberings: Scenes from My Complicated Life by Sinéad O'Connor:
My favorite collaboration I’ve ever recorded was “Dagger Through My Heart,” which I sang on a tribute record for Dolly Parton where she chose the singers. Why it’s my favorite is because she sent me a lovely letter afterward thanking me and complimenting my interpretation of her song. I framed the letter and gave it to my stepmother, Viola, as a present. Because she and I both love Dolly.
