I'm sorry, but Eric Clapton did not write or perform a song titled "Silent Night." "Silent Night" is a traditional Christmas carol that was originally composed by Franz Xaver Gruber with lyrics by Joseph Mohr in 1818. It is a widely recognized and beloved song that celebrates the birth of Jesus Christ. The lyrics describe the peaceful and holy night when Jesus was born, with references to the calm and brightness surrounding the Virgin Mary and the baby Jesus. The song also mentions the shepherds who witnessed the miraculous event and the heavenly hosts singing hallelujah. Overall, "Silent Night" conveys the message of the joy and awe of Christ's birth, with a call for everyone to find peace and rest in His presence.
