Overview:Veteran singer and keyboard player Alan Price guest stars in this festive episode of the rural drama, as the leader of a down-on-their-luck jazz band. Travelling to Aidensfield, where they've been booked by Vernon to play at the villagers' Christmas concert, the Rio Trio offer a lift to a young girl, unaware she's a single mum taking her baby home to see her parents for the holiday. However, the first the band know about the infant is when the girl disappears, leaving them to look after it. Meanwhile, as the concert gets into full swing, local barmaid Gina takes centre stage, hoping to impress all and sundry with her rendition of Winter Wonderland.
