Over the past three decades, many songs produced by Rock Records became instant hits. Yu Quan sang their signature song "Rainbow" and "You're the Most Beautiful", which generated a full house karaoke. While Kong Leung and Pin Guan united on stage to sing their hit "Palm", after being separated for years, brought back youthful memories of many audience members.

Rene Liu and Jasmine Leung took to the stage to sing their numbers "It's a Pity It's Not You" and "After", which brought the gig to its grand finale.

The concert chronicled songs labeled by Rock Records that made a mark on the Mandarin pop, and more importantly it recalled cherished memories of fans about a bygone era.
