How thrilling. A Hallelujah 'Flash-Mob, in the middle of a Mall, in the middle of a quick Mall snack, in the middle of shopping Mall madness. Thanks to SJ Rozan for posting the video on her Facebook page where I picked it up. I've watched it several times and loved it more each time. What a splendid thing.
Obviously, as S.J. says, this was rehearsed so it's technically not a real flash-mob type occurrence, but hey, it's close enough and who cares about 'the how' of if when the result is so spectacular.
Thanks so much, S.J. for passing it on.
