And I say, "No, it's not brave at all, because if you ask for something that Derek doesn't know, you're invited to come and sing it first, and then he'll pick it up."  So just be thoughtful before you suggest something too outlandish.
我会说：“那一点也不大胆， 因为如果你选了德里克不知道的曲子， 你可以先上台来唱 然后他就会弹了。” 所以在选太偏的曲子前可要三思
