The song sank into undeserved oblivion; alas, "oldies" stations are really "oldies Top 40 stations," so they don't play a lot of very good songs of the era they supposedly feature. It resurfaced briefly with Enya's "Orinoco Flow," because it had serious pizzicato that reminded people of the earlier song.
"Can't Get Used to Losing You" should make a similar resurgence now, because there's a recent Geico commercial that uses pizzicato in the background that is even more blatantly reminiscent of the song. If I can find a link to a YouTube version or an mp3 of the song, I'll provide a link or embed it here so you can hear for yourself.
UPDATE: For other venerable flatulences, here are the lyrics--attributed to "The English Beat". Given the date of that group, I'm sure that's a cover.
UPDATE: It was #2, not a minor hit at all, for Andy Williams, in 1963. It helps to use the right lyrics--I remembered "Can't get over losing you," but it's "Can't get used to losing you", and despite my thinking it was a Bacharach-David song, it was written by Jerome "Doc" Pomus and Mort Shuman.
UPDATE: Speaking of similarities, I swear I wasn't thinking of C.S. Lewis's That Hideous Strength when I wrote this. I haven't even read it.
UPDATE: Duh! No wonder I couldn't find it. It's an Allstate ad, not GEICO.
