We're counting down the 12 Days of Christmas with daily mini-episodes spotlighting a classic holiday song and featuring an interview with the writer. On this second day of Christmas, we explore Stevie Wonder's "Someday at Christmas" with co-writer Bryan Wells. The former Motown staff writer, who also co-wrote Stevie's Top 10 hits "A Place in the Sun" and "Yester-Me, Yester-You, Yesterday," tells us all about the writing of the holiday hit that's since been covered by The Jackson 5, Diana Ross, The Temptations, Jack Johnson, Justin Bieber, and others.
