"For All We Know" is a soft rock song written for the 1970 film Lovers and Other Strangers, with music by Fred Karlin and lyrics by Robb Wilson (Robb Royer) and Arthur James (Jimmy Griffin), both from the soft rock group Bread.

Richard essentially did as requested and replaced Feliciano's guitar intro with that of Earle Dumler's oboe.

[5][6] When the original song was nominated for an Academy Award, the Carpenters were not allowed to perform it at the ceremony because they had not appeared in any film.

In 1972, Richard and Karen appeared on Tom Jones's London Bridge Special, where they performed "For All We Know".

[citation needed] Petula Clark gave a heart-rending version of the song during her show at the Albert Hall on February 6, 1983, in tribute to Karen Carpenter, who had died two days before.

[14] English singer Nicki French released a cover of "For All We Know" in 1995, which was included on her debut album, Secrets (1995).

Steve Baltin from Cash Box wrote, "French follows up her surprise dance hit cover of Bonnie Tyler’s "Total Eclipse Of The Heart" by giving the same treatment to the Carpenters’ "For All We Know".
