"Get The Words Right"

Good Morning and happy Sunday.
Why do most of us get the lyrics wrong...when we sing a song to ourselves in the car or shower. It's because we haven't listened or we misunderstood the words from the singer. I find my self singing the wrong words or making something up because I don't know the real lyrics, then I can't get them out of my head ...., there stuck in the brain all day...Christmas tunes are the worst....Our Elvis look a like has done it to me to, I can't get "hot dog frying all the time" out of my head. Enjoy the day and be ready for Monday. Robbay
