Some pretty 'convincing' arguements from industry 'pros'. Can't ignore that, however, the eyes don't lie and watching A New Journey closely (haven't seen the Helix show yet so can't comment) will reveal there is no 'miming' on the DVD. As GUEST Kat pointed out, watch the breath (you can actually see it at some points), listen to the breath, and watch the throats, if you will, especailly Lisa Kelly during 'the voice'. It is possible some post dubbing was done to clean up the soundtrack, but when you see the girls singing on stage, that is what you are hearing. I guess this arguement will go on until the end of time, and probably more artists 'mime' than we would like to think, its just that I dont think ANJ falls into this category, and since I have not seen CW in concert, I cannot comment on that (but I know they dont need to). Thank you for listening.
