"[4] Bryson and Flack had previously appeared on the R&B chart in Billboard with two duet singles: "Make the World Stand Still" and "Love is a Waiting Game", both from their collaborative 1980 Live & More double album.
"Tonight, I Celebrate..." was afforded further international success charting in Australia (#10), Canada (#4), Finland (#13), Flemish Belgium (#8), Ireland (#5), the Netherlands (#16), New Zealand (#11), Norway (#8), and South Africa (#4).
Directed by Martin Pitts, the video was a straightforward performance video showing Flack and Bryson singing the song—she playing the piano and he seated on a stool at her side—while session musicians may be seen in the background: the clip was taped at the Capitol Studios in Hollywood, the Born to Love album being recorded for Capitol Records—Bryson's home label—with Flack on loan from Atlantic Records (the track "Tonight, I Celebrate ... " was in fact recorded at A&M Studios with Randy Kerber on piano: Flack did not play piano on any tracks on Born to Love).
"Tonight, I Celebrate ... " would also be the only major hit duet for Bryson and Flack in the UK where "Heaven Above Me" was issued as the follow-up single to chart no higher than #84.
Bryson would however score two more top 10 hit duets in 1991 and 1992, with "Beauty and the Beast" and "A Whole New World" respectively; the latter a number one on the Billboard Hot 100.
