Charming vocalist with a delighful Ella-influenced style, Caleb – who has worked with Jim Mullen, Soweto Kinch, Robert Mitchell and Gary Husband et al – appears here singing a Christmas special with Roberts who is way above the hordes of average Sinatra wannbes out there; he is a crooner cut from similar cloth to Kurt Elling and Mark Murphy.
