The Summer of What Now?

Most people think Bryan Adams is singing about a year in the song Summer of 69. Apparently not.
Adams appeared on a talk show in New Zealand. The host mentioned that since Adams was born in November of 1959, he would have been only 9-years-old that fateful summer.
Adams replied, “It’s not about a year. It’s a metaphor. I never said 1969.” The host responded, “Oh, It’s a metaphor for that?”
Adams said, “It’s a metaphor for a great summer.” The host responded, “Of love?” Adams said, “Summer of love, exactly! Thank you very much.”
I always had my suspicions, but nothing to confirm them. Cat’s out of the bag now. Bryan… you dirty dog.
