Last Night (Az Yet song)

"Last Night" is a song by American R&B group Az Yet, produced by Babyface and Mervyn Warren, and released as the first single from the group's debut album, Az Yet (1996). The song became the group's first hit, reaching number nine on the US Billboard Hot 100, number one on the Billboard Hot R&B Singles chart, and number four on the Billboard Top 40/Rhythm-Crossover chart. Additionally, it reached number two in Australia, number six in New Zealand, and number eight in the Netherlands. The song was also included on The Nutty Professor soundtrack.

Critical reception
Larry Flick from Billboard viewed the song as "yet another gem" from the soundtrack to The Nutty Professor. He added, "Az Yet is a charismatic male quintet that aims to come across as a mature alternative to the army of smooth groups currently vying to harmonize their way to the platinum land owned by Boyz II Men. Honey-soaked notes are poured over old-school soul music carrying the unmistakable stamp of producer/writer Babyface (does this man ever take a nap?). Engaging as can be." Peter Miro from Cash Box felt that "Last Night" "is the most potent offering on their 12-track collection of ballads, with lyrics ladies will cling to endlessly." A reviewer from Music Week rated the song four out of five, adding that "the Philadelphia soul quintet show they are the masters of close harmony vocalising on this seductive debut". Ralph Tee from the magazine's RM Dance Update said, "Already a Billboard hit, and also on the Nutty Professor soundtrack it's a touch MOR vocally, though the harmonies are the standout feature beneath the shuffle beat rhythms."
