"This is the best trip, I've ever been on"

Just want to know the words to that song the Cardiff fans are chanting at the moment, I can make out something like "As the Cardiff boys set sail, can't hear the Swansea sing, we are the Cardiff boys and we'll sing on our own, don't wanna go home, don't wanna go hoooome, this is the best trip I've ever been on", but I'm not exactly sure if those are the exact words
