About half of the tracks on Bert and Ernie Sing-Along are popular originals from the series written by the likes of Joe Raposo. Delightfully, "Morningtown Ride" by Malvina Reynolds gets a cover version, a sure sign of a hipster lurking in the wings. It could be Sam Pottie, who has quite a few fingers in the pudding as composer or co-composer of many numbers while handling the total sum of musical arrangements as well. "I Refuse to Sing Along" may set a typically cynical Muppet point-of-view, but the album at the same time makes no effort to avoid the inclusion of singalong fodder: "I've Been Working on the Railroad," "Old MacDonald Had a Farm," "On Top of Old Smokey," and so forth. Still, Ernie's rendition of "On Top of Old Smokey" makes all others obsolete.
