Principal Tam put on a magnificent show filled with classic hits that define a generation, from "Late Spring" and "Love Trap" to "Half Dream, Half Awake" and "Silent Gratitude," not to mention his most recent 40th anniversary theme song "Galaxy Years." Jacky Cheung, Eason Chan, Priscilla Chan, Hacken Lee, Kelly Chen and, of course, the other members of Wynners appeared as special guests for different nights of the concert tour.
