Alyson and Amanda Michalka of Aly & AJ posted an old home video of the pair singing at a Christmas service at church when Aly was 8 and AJ was 6. They write, “We figured, in the spirit of the season, we’d post up some old videos from when we were just starting our singing careers! Haha. There were 1,500 people at our church so it was a little nerve racking.” Watch the siblings and other kids in the choir performing ‘Hark! The Herald Angels Sing’, ‘O Come All Ye Faithful’, ‘Joshua Fought The Battle Of Jericho’, a solo by Aly, and a one-toothed AJ singing with her mother below.
