Just for the record (an' I only know coz I was told on the other a cappella thread) A cappella (2 p's) is in the style of the church (cappella=chapel)- there is a reason a church is cappella as well - see the other thread. A capella (1 p) would be in the style of the hair! (capella=hair)So I have no chance of singing A capella, having no hair to go at!
