The Elements (names of chemical elements to tune of “Modern Major General”)

Official recordings by Lehrer
* 1959-03-20 live, released on An Evening Wasted With Tom Lehrer; there are at least two versions found on Lehrer's releases. The time ranges overlap and both have been confirmed on VA compilations, so be careful with merges!
** The Reprise vinyl releases (judging by printed times), The Remains of Tom Lehrer and some other compilations start The Elements with "Now, let me digress..." and end with Lehrer asking for the next slide. Usually ~2:10-2:14 but can be longer.
** The 1990 CD and a few other CD and digital versions start immediately following A Christmas Carol with "Actually, I've done rather well..." and end immediately following The Elements. Asking for the next slide is found on the following track, Oedipus Rex. Typically ~2:19, but also can go longer.
* 1959-07-08 studio, released on More of Tom Lehrer, length ~1:23-1:26
