Originally called The Flashy Ladies, a reference to a song on Manilow's first album, the trio (with Ramona Brooks, whom Pege replaced in 1976) sang backing vocals for Manilow in live performance and on his first seven multiple platinum albums.
They performed with Manilow on his first European tour in 1978 with concerts at the Olympia in Paris, The Palladium and Royal Albert Hall in London, and the Concertgebouw in Amsterdam.
Because Pege and Byrd were African-American, and Reparata, in the middle position, was Caucasian, Manilow often jokingly referred to them as "The Oreos.
Monica Pege sang with Barry Manilow again from 2004 to 2010 in Las Vegas at the Hilton and his Colosseum shows.
In 1984, Pege was crowned the Female Vocalist grand champion on the debut season of Star Search.
