I don't know if S Club 7 lipped, hmm, I doubt they would have on tour and I'm sure I've seen some live performances from them, they lipped on TOTP a few times obviously but other then that I don't know. I mainly watched their tv show
But yes, they did have more choreography (regular pop standard with a few backflips) because it would look silly with 7 on stage hardly doing anything lol.
I'd like them to return as well or at least see more of Jo, I wonder what ever happened to the S Club Juniors...
