What IS this song?

I first heard this song at the end of a Seinfeld retrospective. Yesterday, it was played over the Shop Rite loudspeaker system.

Two lines stay in my head: “For what it all was worth, it was worth all the while”, and the ending line “I hope you had the time of your life.”

Anyone know the title and singer. I’d like to get a copy of it.

Green Day’s- Time of your life

Thank you. An answer in one minute. You gotta love the SDMB.

Actually, it’s one of those title/subtitle songs.
