I had selected Mr. John* to be as the Head Perfect for the year 1973. Now he's come came back to thank us, and the school.
He he's donated one thousand $1,000 to the school.

* While it's possible, it's unlikely that the person's surname is "John". In English, we do not typically use Mr + [first name]. We use Mr + [first name surname], or Mr + [surname].
For example:
Mr John Connolly.
Mr Connolly.
Mr John.

Also, note the use of the present perfect he's (= he has). The present perfect connects the past with the present.

"While it's possible, it's unlikely that the person's surname is "John".
How about: Elton John, Olivia Newton John, Tommy John et al.?

I have two questions:

1. Why use the past perfect tense in the first sentence? I think the past tense is more appropriate.

2. Is it selected as or selected to be?

"While it's possible, it's unlikely that the person's surname is "John".
How about: Elton John, Olivia Newton John, Tommy John et al.?

I didn't say it was wrong. I said it was unlikely. Reread my comment. I still say that "John" is typically a first name, not a surname. Oh, and by the way, Elton John's real name is Reginald Kenneth Dwight.

1. Why use the past perfect tense in the first sentence? I think the past tense is more appropriate.

Either tense is possible in the above. The past perfect works because the "selection" took place prior to the "coming back", with a significant period in between, during which many other events are assumed to have taken place.

2. Is it selected as or selected to be?

I prefer "as".
