Matt Walker and his troupe of Troubies continue their improbably consistent successful run of holiday comedies, blending Christmas storylines with a defined canon of music. In years past, the productions were “It’s a Stevie Wonderful Life” and “A Charlie James Brown Christmas.” I am hopeful they will bring back a few shows I missed, like “A Christmas Carol King” or “Santa Claus is Comin’ to Motown” or “Little Drummer Bowie.”
