"Legend of a Mind"

I'm fairly certain that the second (and also the fourth) section of "Legend of a Mind" contains the lines "Takes you trips around the bay / Brings you back the same day" (I might be wrong in my transcription).  There's parallelism between "Takes you trips" and "Brings you back."  Both are alliterative, and the word order is similar ("Takes you trips" / "Brings you back" - [verb][direct object][word that alliterates with the verb]).

More interesting, though, is the section half-way through (~1:52), where the length of the lines increases:

Along the coast, you'll hear the most about a light they say that shines so clear
So raise your glass, we'll drink a toast to the little man who sells you thrills along the pier
He'll take you up, he'll bring you down, he'll plant your feet back firmly on the ground
He flies so high, he swoops so low, he knows exactly which way he's gonna go

The rhyme scheme here is the interesting thing.  The first two couplets rhyme with each other ("clear"/"pier"), but the last two couplets seem like they're each two couplets re-arranged into a single line.  So they could be re-rendered as

He'll take you up, he'll bring you down
He'll plant your feet back firmly on the ground
He flies so high, he swoops so low
He knows exactly which way he's gonna go

Later in the song (~5:01), they do appear almost in that form:

He'll take you up, he'll bring you down
He'll plant your feet back on the ground
He'll fly so high, he'll swoop so low
Timothy Leary

But in that lengthened verse, the internal rhyme is key.  "Coast," "most," and "toast" are irrelevant to the rhyming of the first two couplets, but they act as an indication of what the rhyme scheme will become.  The words that are in the same position in the line as "most" and "toast" (the words that the eighth syllable falls on: "down" and "low") will become important in that new rhyme scheme:

Along the coast, you'll hear the most about a light they say that shines so clear
So raise your glass, we'll drink a toast to the little man who sells you thrills along the pier
He'll take you up, he'll bring you down, he'll plant your feet back firmly on the ground
He flies so high, he swoops so low, he knows exactly which way he's gonna go 

That internal rhyme acts as a sort of structural foreshadowing.

There are also a couple phrases for which the melody provides a musical representation.  "So raise your glass," "He'll take you up," and "He flies so high" ascend (E A B C#); "He'll bring you down" and "He swoops so low" descend (E' C# B A).  When that "He'll take you up..." section is revisited (~5:01), the "down" and "low" are sung with descending melismas (E to D).  Similarly, the end of "back on the ground" descends (a string of F# notes to an E).

At about 2:22, there's a brief change in meter (a duple meter becomes a triple meter).  I think this is intended to represent the mind-altering effects of Leary's drugs.

In all three of the live versions I have in my collection, Mike Pinder plays the "Charge" fanfare (or something close to it) on mellotron after the line "Along the coast, you'll hear the most about a light they say that shines so clear" (although in some of the versions, it sounds more like "life" than "light").  In chronological order:

• 12 December 1969 (Caught Live + 5), ~2:17
• 17 December 1969 (bonus track on To Our Children's Children's Children), ~1:04
• August 1970 (Live at the Isle of Wight Festival 1970), ~1:49
