Love this song. Richard Carpenter wrote it after hearing a bank commercial jingle/ad, that just had the title line. The ad music was written by Paul Williams, IIRC.
Karen was also a talented drummer, before becoming a legendary singer.
Word around the campfire was that John Wayne wanted her to be in True Grit in the role Kim Darby played. And that Elvis Presley was highly considered for the role Glen Campbell played. TG would have been a totally different movie had that happened.
The song I believe was for Crocker Bank which was brought out by Wells Fargo which still exists.
