Question: Along with her song "Will You Still Love Me tomorrow" which made 76 on the Hot 100, Roberta Flack has also performed many duets, including "Where Is The Love" with which singer?
Context: "Tonight, I Celebrate My Love" is a song written by Gerry Goffin and Michael Masser recorded as a duet single by Peabo Bryson and Roberta Flack and released in 1983.  It became a big hit for both singers, peaking at number sixteen on the "Billboard" Hot 100, number five on the Hot Black Singles chart, and number four on the Adult Contemporary chart.  In the UK, the song peaked at number two in September 1983.  In addition to becoming the biggest British hit for both Bryson and Flack, the song boosted the careers of both stars and brought them both a return to prominence.  Capitol Records' Bob Hart asked Martin Pitts to Direct the official video through One Heart Productions.  The video was a performance with the original band in the background at the Capitol studios on Vine Street in Hollywood. 20/20 is a studio album by George Benson, released on the Warner Bros. record label in 1985.  The lead single by the same name reached #48 on the "Billboard" Hot 100.  The album was certified Gold by the RIAA.  "You Are the Love of My Life" is a duet with Roberta Flack; it was one of numerous songs used for Eden Capwell and Cruz Castillo on the American soap opera "Santa Barbara".  Also included on "20/20" is the original version of the song "Nothing's Gonna Change My Love for You" which would later become a smash hit for Hawaiian singer Glenn Medeiros. "The Closer I Get to You" is a romantic ballad performed by African American jazz, soul, R&B, and folk singer-songwriter Roberta Flack and African American soul musician Donny Hathaway.  The song was written by James Mtume and Reggie Lucas, two former members of Miles Davis's band, who were members of Flack's band at the time.  Produced by Atlantic Records, the song was released on Flack's 1977 album "Blue Lights in the Basement", and as a single in 1978.  It became a major crossover hit, becoming Flack's biggest commercial hit after her success with her 1973 solo single, "Killing Me Softly with His Song".  Originally set as a solo-single, Flack's manager, David Franklin, suggested a duet with Hathaway, which resulted in the finished work. "I Still Love You" is a song by the American folk rock band the Vejtables, written by Jan Errico, and first appears on the group's debut single, which was released on Autumn Records in 1965 ("see" 1965 in music).  The Vejtables were signed to the record label after receiving some regional notice on the nightclub circuit, despite all the band members still were enrolled in high school.  "I Still Love You" exhibits influences from their label-mates the Beau Brummels, though it is largely marked by its jangling 12-string guitar arrangements, folky vocal harmonies, and sparse use of the harmonica.  Arguably the Vejtables' greatest asset was Errico, who not only penned the song, but also played drums, making her one of the few 1960s female musicians to do so.Upon release, "I Still Love You" reached number 83 on the "Billboard" Hot 100, becoming the only Vejtables release to crack the chart.  The song charted quite respectably in Chicago.  It debuted on the 10th of September, and 3 weeks in the charts, finally peaking at number 23 on the 24th of that month. Quiet Fire is the third studio album by American singer-songwriter Roberta Flack, released in November 1971 by Atlantic Records.

"Where Is the Love" is a popular song written by Ralph MacDonald and William Salter, and recorded by Roberta Flack and Donny Hathaway.

"Billboard" ranked it as the No. 58 song for 1972.  The song won a Grammy Award for Best Pop Performance by a Duo or Group with Vocals.
