Looking out into the audience, senior Jack Mullen solos “Have Yourself a Merry Little Christmas” by Frank Sinatra at the annual winter choir concert on Dec. 10. Mullen volunteered to sing a solo to aid the transition between choir groups on stage. “I chose that song because I really like the crooner genre when it comes to holiday music. [That song] had all the element[s] of Michael bublé, Nat King Cole, Frank Sinatra and Bing Crosby. Also, it’s a simple melody, so I did vocal gymnastics when I could and made it my own,” Mullen said.
