Where's my Asian friend again?

The story:

I was at a school fundraiser and there was live music. One of the bands was playing this song as a cover. All my friends and I were being really stupid and singing at the top our lungs. Well when it came to the chorus, I sang the wrong lyrics and my friends just cracked up. They have never let me live it down.
But what's funny about it is that in the band, two of the members were asian. My friends made matters worse by then shouting "The're right there, duh!"
