I Wasn't the One (Who Said Goodbye)

"I Wasn't the One (Who Said Goodbye)" is a duet by Swedish singer Agnetha Fältskog and American singer Peter Cetera, formerly the lead singer and bass guitar player for rock band Chicago. The track was recorded for Fältskog's third English language studio album I Stand Alone (1987). It was written by Mark Mueller and Aaron Zigman, with Cetera providing production. It was released on 22 February 1988 as the second single from the album. A Spanish language version of the song, "Yo No Fui (Quien Dijo Adiós)", was also recorded and included in South American versions of I Stand Alone.

It proved arguably the album's biggest chart success, peaking at number 93 on both the Canadian RPM Top 100 and US Billboard Hot 100 charts; it was also a top twenty hit on the AC charts in both countries. Like usual, Fältskog did not do any promotion for the single in North America.
