Music This is real find. Potentially Tom Lehrer's greatest contribution to education is his song The Elements, which in some schools is the primary way in which the children learn about the chemical elements because they've been put to fairly recognisable tune, except in my school where no one had heard of him.
Anyway, this very morning, I've discovered that there was an earlier version of the song, with all the same elements but not in quite the same order and it was recorded live in Copenhagen in 1967. Having heard the version on his "An Evening Wasted With..." live album so many times its strange to hear it done quite this differently and with a whole different set of ad-libs.
Found here at the home of improbable research. There'll be a short quiz next period.
