Question

I tried to change this sentence to indirect question
3) what was the moment when you finally said I am an Irish rocker but I’m also now fully engaged in this topic?

Indirect question

He asked Bono what had been the moment when finally you had said you are an Irish rocker but you are also now fully engaged in that topic.

Answer 1

Change each 'you' to 'he' and adjust the verbs to match. What do you get?

Answer 2

He asked Bono what had been the moment when finally he had said he is an Irish rocker but he is also now fully engaged in that topic.

Answer 3

That's a bit wordy. Try this:

<i>He asked Bono exactly when he had finally said he was an Irish rocker, but was also now fully engaged in that topic.</i>
