I always played:

[E] History lesson, it's time to re-[B]-member
[E] Time to remember the deeds of the [B] great
[A] Please pay attention, don't let you mind [E] wander
[E] Daydreams and playtime can wait
[E / E7] Black the minnows that [B] swarm in the [E] water
[E] White, the [B] butterfly [E] flits in the [B] sun
[E / E7] Red, the blossom, and [B] pink the mag-[E]-nolia
[E] History Lesson's be-[B]-gun...

A very basic arrangement - there may well be alternative chords.
