Years ago, I mentioned to a co-worker that I thought "Wassail, Wassail" was one of the Christmas carols Mannheim Steamroller performs best. She surprised me by singing the first verse of it. I thought, "You win the farmer's market poll, then. If I surveyed 10 random people, most respondents would say they haven't heard of 'Wassail, Wassail' or would confuse it with 'Here We Come A-Wassailing.' A smaller number of respondents would be familiar with the carol but wouldn't be able to match Mannheim Steamroller's instrumental rendition with its lyrics. Well done..."
I still think "Wassail, Wassail" is one of Mannheim Steamroller's best tracks; its lack of an overly synthesized arrangement makes it work for the same reason as their version of "In Dulci Jubilo."
