“I Will Wait Again, I Will Look Forward To It More. You Have No Idea How Many People Endured Hardships For The Longest Time To Prepare This Concert. Among Them Are All The SONEs Who Believed & Waited Until The Very End. I Truly Feel Once Again How Happy I Am. My 28-Year-Old Self, This Precious Moment. My Precious Fans.” - Taeyeon, Girls’ Generation 

“On July 19, 2007, Girls’ Generation had their first performance on M.Net Countdown. Although this performance was never broadcasted on television, many fan-cams were shot and uploaded onto the internet. The song the girls performed to was called “Into the New World”, which would end up being their first single.” (x)
