Sung a while back by Coventry fans when a bride and groom appeared on the pitch, away at Charlton.
You don't know what you're doing, You don't know what you're doing, You don't know what you're doing, You don't know what you're doing...
A wicked Coventry City chant to sing, gets the crowd going. Great ringtone.
Simple, to the point and passionate. Always sounds good on the mobile.
