Christmas with Eric in That's Rock 'N' Roll Posted December 5, 2012 LC said: I think I remember that episode -- wasn't that a kids-melt-Grinchy-character story line? Not bad at all! Actually, it was the "grizzled but kindly loner" in a ghost town telling a story about the town's history in which the Partridge crew played old west denizens of the town (another tried and true sitcom angle). The old man was never grinchy, rather Reuben Kincaid played the grinchy guy from the past. The grizzled guy teared up because he thought he was spending Christmas alone (once the Partridges fixed their ailing bus), but they felt sorry for him and came back to spend Christmas with him. Nice episode, nice song.
