Michael Steven Bublé OC OBC (born September 9, 1975) is a Canadian singer. A four-time Grammy Award winner, he is often credited for helping to renew public interest and appreciation for traditional pop standards and the Great American Songbook. His musical influences include Frank Sinatra, Dean Martin, Sammy Davis Jr., Tony Bennett, Nat King Cole, Bobby Darin, and Elvis Presley, and Sam Cooke.

The Puppini Sisters are an English close harmony vocal trio composed of Italian-born singer Marcella Puppini and English singers Kate Mullins and Emma Smith. Although the three are not related, the name was chosen in tribute to the Andrews Sisters. They are known for providing guest vocals on Michael Bublé's cover of "Jingle Bells". Puppini first studied fashion design at Saint Martins School of Art, and later music at Trinity College of Music in London where she met Mullins and original member Rosanna Schura, who was later replaced by Stephanie O'Brien. After eight years with the group, O'Brien was replaced by Emma Smith. The trio are backed by a three-piece band featuring Martin Kolarides on guitar, Henrik Jensen on double bass and Peter Ibbetson on drums. The group is associated with a burlesque revival.
