best one chord song?

I'd just like to say that it's _my favourite thing ever_ when there is a triad or an open 5th that drones on for the song's entirety... chord changes, bass movement may happen, but that chord stays on, regardless. "2nd Thought" and "Of all the things we've made" by OMD are key examples

Yeah, 'Of All The Things We've Made' is great. Love the way the bassline moves around while the guitars stay on the one chord throughout.

drunks with guns - hell house, iirc?

love thy will be done IS NOT a one chord song, try humming the vocal melody and you will realise there are at least 2 or 3 chord changes during the verses

yeah, that's what I always thought but listening to it recently, I realized the bass stays on the one note the whole time. of course there are some other notes played by the synth and I agree that it feels like there are more chords though.

Bo Diddley wrote sarky songs to Chubby Checker? Oh hang on...

eheh, listening to "Love Thy Will Be Done" on the Prince Originals comp made me think of this thread... only to find out I had already written the EXACT same thing I was planning to post !
Ageing memory...
Regarding "Tomorrow Never Knows" I think I remember McCartney actually saying in the Anthology or something that Lennon was just strumming the C chord throughout the song and how unusual and new it was for them.

Sheets of Easter, of course
