At the time it was released, Lifes Rich Pageant became the highest-charting R.E.M. album, as it reached #21 on the charts. Of course, the group would go on to have two #1 and three #2 albums later in their career. "Fall on Me" was not a big hit, but it did chart, reaching #94.
The video for "Fall on Me" was directed by lead singer Michael Stipe, and consists of words (mostly from the song's lyrics) that flash over upside down footage of a quarry in Indiana. For extra points, one word in the video is famously misspelled; see if you can identify it without resorting to Google.
Note that R.E.M.'s first single "Radio Free Europe" was posted on ERV back in September 2011, when the band officially broke up.
