Disappointing correct lyrics

Yesterday, a song by Coldplay came on the radio.  I must have had it on louder than usual, for I could hear the lyrics clearly.  I was most disappointed to discover that one line of it really goes:

"Roman Catholic Choirs are singing"

I feel that the version I'd previously always managed somehow to hear is greatly preferable, summoning up as it does images of great choirs of heavily armoured Sarmatians on horseback:

"Roman Cavalry choirs are singing"..
