I have a friend who likes to sing. A lot. To be fair, shes got a good voice, but a terrible inability to hear and understand lyrics.
Accordingly, until I corrected her after having heard her sing the whole song through while trying to prevent my overburdened ribs from ripping apart, she had spent quite some time under the mistaken idea that Abba had in fact brought out a song in the seventies called "Chicken Tikka".
It never fails to amaze me that it never occured to her that might be not quite what they were singing, or that Chicken Tikka might not have been around in 1970s Sweden for them to make up a song about.
Being a very longstanding Abba fan, I await the day they reunite and record the sequel - Chicken Pizza, or Chicken Fajita. Whichever they fancy most at the time, I suppose.
