Pre-’68 rock/pop songs over 10 minutes

Chad and Jeremy were a UK duo that were far more popular in America than they were in Britain. I think they appeared post The Beatles/British Invasion. Their biggest hit was 'Yesterday's Gone' and I can't say I've ever heard any of their other work.

I Heard It Through The Grapevine is from Creedence Clearwater Revival's album Cosmo's Factory, which is from 1970.

I don't think there is an early version pré-1968

Another song - The Chamber Brothers - Time has come today (1967) (psychedelic rock/soul) 11 minutes and some seconds.

Any help? June 1968 - and it was a collection of related songs joined together with odd folky music and the story of Happiness Stan and Mad John, narrated by Stanley Unwin. A side-long concept, no less. To add to the list: Fifty Foot Hose: "Fantasy" ("Cauldron") - 1967 (10:13). Also under consideration: Nirvana: The Story of Simon Simopath (1967) - a concept album that predates "SF Sorrow".

When talking about concept albuns it is sometimes difficult to distinguish suites from separated songs liked by a concept.

To make the things more clear, let's state a thing: a group of songs cannot be considered a suite unless it is explicitly written in the original album.
For example: Days of Future Passed cannot be considered a single song, although it is a concept album, since there is no indication that the songs were made as a suite.
Karn Evil 9 can be considered a suite although in the record, the length of the parts is separated, since the songs are named Karn Evil 9 - part 1, part 2, so they are part of one song.
Ballet for a Girl in Buchannon  can be considered a suite although the parts have all different names, because you can get this info in the album.

Do you agree?
