I went through a Donovan phase in high school and never stopped loving his music, though I didn't realize at the time (when I had more admiration for the '60s and hippies -- today if I had been around in 1968 I'd have voted for Nixon. Probably.) -- I didn't realize at the time how cringy and ridiculous it all was.
"The Walrus and the Carpenter" is the first track on H.M.S. Donovan, a double album mostly of short (1-3min) children's songs and nursery rhyme settings. It's actually a really great record though it bombed because it wasn't really conducive to singles (though "Celia of the Seals", a minor hit, is pretty good). The problem with "Walrus" is that it's eight minutes long, twice as long as anything else on the album, starts the album, and sounds like nothing else on there. It's not even really a song, just reciting a story by whoever wrote it, with goofy sound effects and sped-up and slowed-down voices. It fits with the album in that it's an adaptation of a children's story but god damn.
I guess I agree with "Seriously", but I'm never budging on "World in Motion". It's not just the rap part, though that's bad; I hate this term but it screams corporate-sellout. The chorus is annoyingly bouncy, too.
