From Sputnik Music‘s review of “In the Days of the Cavemen,” from Crash Test Dummies‘ 1993 album God Shuffled His Feet: “Oh Canada! Hail to my neighbor to the north. I praise you because not only have you shared with us some major musical talents over the years, like Rush and Joni Mitchell (for which I am eternally grateful), but you’ve also given us a host of quirky smaller bands throughout the last four or five decades, so many of whom I’ve enjoyed: Bands like Klaatu in the seventies, and Martha and the Muffins in the eighties. Oh, and in the nineties — Crash Test Dummies!
Although they made a nice little career for themselves in the great white north, God Shuffled His Feet was this band’s only internationally successful album … (It) took off around the world … powered by the success of one unconventional single, a slow and poignant track about how it feels to be different, the oddly- titled ‘Mmm Mmm Mmm Mmm'”.
Brad Roberts’ voice is quite unusual for a frontman, given its edge-of-the-bell-curve bass/baritone range. Adding to his immediately recognizable sound are the relatively slow pace of the lyrics and his habit of over-enunciating: it often seems as if he’s passing on time-sensitive directions on how to diffuse a bomb — over the phone, to a middle school student. Roberts also was central to the band as an instrumentalist. Frequent contributor JB adds: “The bassline is exquisite throughout the whole tune: clean and melodic, but the same can be said of almost every bass part played by Brad Roberts.”
The tune is set in B major for the verses and the chorus; there’s a big jump to G major for a bridge at 1:35 – 1:54 (or rather a bridge-like section, because it happens again at 2:37 – 3:16).
