The show started as a senior citizens show for psalms and traditional songs. It wasn't intended to be a concert. Half of them probably got a Hart attack
It's very common for singers that also dance to have "back-up vocals" (which are basically the ones from the record) playing while they perform, but fairly quietly, and then they have a live mic for singing over the top. Madonna pioneered it back in the eighties because it's really hard to sing properly when you're out of breath from dancing. So it's not "mimimg" as such. It's singing over the top of pre-recorded vocals. For this performance the back-up vocals are a little loud (so it sounds just like the record at the start) and then it's obviously revealed to be "on tape" when she drops the mic and the vocals continue.
@Ivestor1 I asked my local radio station to play Robyn. Their response: "Never heard of her. Will try to check her out". Really. That was their response. I guess they'd rather play Ke$ha or Britney...puke.
did she play other songs or it was just a one-track theme park special? how did this not get the number 1 in the uk *DOES NOT COMPUTE* its AMAZING!!!! also, love the band at the back tapping their feet along to the music :) tack for the upload!
