Singing Sierra is back, and just in time for Christmas.

Adam Yamada-Hanff, a Baltimore area community college student, has posted several videos on YouTube of Sierra “singing” as he plays his saxophone. This latest one also features Cody, who clearly considers himself a backkground vocalist.

We met Sierra and Adam back in May, when they — well, Adam, anyway — agreed to a quick sidewalk performance during my “Hey, That’s My Dog!” photo exhibit at Captain Larry’s, a bar and restaurant on Fort Avenue in South Baltimore.

Adam uses Sierra’s singing abilities to help raise money for animal shelters and rescue organizations.
