Nile Rodgers, the album's producer, called it "the best thing I ever made that didn't sell" in the July 27, 2015, issue of New York magazine. "The theme from [the TV series] Moonlighting was on it, but Al and I thought it wasn't cool enough. So we took it off the album. That becomes a hit, and the album sank. Shows what I know."[6] The single version of the Moonlighting theme, originally included on the show's 1987 soundtrack album, was added to Friday Music's 2011 reissue of L Is for Lover along with a remix of the album's title track and the 12-inch extended mix of "Tell Me What I Gotta Do." The Rodgers-produced version of Moonlighting's theme song was used in the opening and closing credits of each episode of the show's fourth (1987–1988) and fifth (1988–1989) seasons.
Richard S. Ginell of AllMusic called the album "a perhaps surprisingly scintillating collaboration with one of the leading dance-music producer/guitarists of the time, Nile Rodgers (of Chic). Not only did Rodgers and Jarreau assemble some strong tunes from many sources, Rodgers took advantage of Jarreau's rhythmic capabilities, for some of the material is too deliciously complicated for any old R&B soulster to pull off." He added, "Hear the way Jarreau brilliantly threads his way through the rhythmically complex hornet's nest of 'Says' in English and French, or savor the sheer ecstatic energy of the chorus of 'Pleasure' and the rapid-fire list of cities in the title track; this is first-class pop recordmaking."[7]
J. D. Considine of Musician wrote, "It isn't simply that Rodgers reins in the singer's almost freakish virtuosity, although that helps; more to the point, the arrangements provide both focus and contrast for the singing, so that the flash bits truly excite. Best of all, from the EW&F swing of 'Golden Girl' to the Chic-style groove of the title tune, Rodgers ties the vocals so closely to the beat that it's impossible not to be captivated."[9]
