Question: band that got in trouble for lip syncing

title: Milli Vanilli
text: Beth McCarthy - Miller , then an executive with MTV , says the duo 's poor English language skills , when they came in for their first interview with the channel , stirred doubts among those present as to whether they had sung on their records . The first public sign that the group was lip - synching came on 21 July 1989 , during a live performance on MTV at the Lake Compounce theme park in Bristol , Connecticut . As they performed , the recording of the song `` Girl You Know It 's True '' jammed and began to skip , repeating the partial line `` Girl , you know it 's ... '' over and over through the speakers . They continued to pretend to sing and dance onstage for a few more moments , then they both ran offstage . According to the episode of VH1 's Behind the Music which profiled Milli Vanilli , Downtown Julie Brown stated that fans attending the concert seemed neither to care , nor even to notice , and the concert continued as if nothing unusual had happened . In a March 1990 issue of Time magazine , Pilatus was quoted proclaiming himself to be `` the new Elvis '' , reasoning that by the duo 's success they were more talented musically than Bob Dylan , Paul McCartney and Mick Jagger .
