My mother was like some others mentioned here - couldn't sing for anything - her forte was drawing & painting; but she loved to recite poems like "Winkyn, Blinkyn, & Nod" to us.
Dad was the singer - mostly pop songs - Nat King Cole, Ella's "A-Tisket, A-Tasket," etc. The one I remember most, because he always picked me up to dance for it had a lyric that included, "Gonna dance with the dolly with the hole in her stockin', hole in her stockin', hole in her stockin'; gonna dance with the dolly with the hole in her stockin', dance by the light of the moon."
His family had singing sessions whenever they would get together (I thought that's what families DID - when I went to holidays at my husband's & found out they went out and played football instead, I was totally dismayed).
A couple of my great-aunts were in vaudeville, so everyone knew a lot of the old songs from that era too.
