There’s a remix that actually has bells

Apparently it’s not a remix, it’s the original.

Despite the song’s title, no bells can be heard in the album recording. The original version of the song, riddled with bells of various types including a cowbell, is 7 minutes and 11 seconds long and was only released on 12 inch vinyl.
