Could you comment on this kind of conditional sentence?

And from to-morrow, if I have sung, as I will sing, to-night, I will dare, (and I dare now to tell you that I will dare, to But before I do dare that word, my own, let me tell you how very prominent I am! ) (The great way: a story of the joyful, the sorrowful, the glorious by Mitchell Kennerley 1921 )

1) if I have sung - When is he going to sing? (tomorrow or tonight?)
2) Is it ok to use Present Simple instead Present Perfect - if I have sung = if I sing
3) as I will sing - When is he going to sing? (tomorrow or tonight?)

1) if I have sung - When is he going to sing? (tomorrow or tonight?)Tonight.
2) Is it ok to use Present Simple instead Present Perfect - if I have sung = if I sing
It would be possible in this sentence, though the writer is implying the previous completion of the singing - in the future:

I will sing - if I sing
I will have sung - if I have sung.

3) as I will sing - When is he going to sing? (tomorrow or tonight?)tonight

This is a very contrived style of writing; do not take it as a model.

Is this combination ok for the real conditional?

If you have called me tomorrow I will tell you everything.???

Does it mean the same as?

If you call me tomorrow I will tell you everything.

There is a difference, though it may not be significant.

In the first, the speaker thinks of the calling as a future completed action. In the second, s/he thinks simply of the future action.

Would my assumption be plausible if I infused the following meanings into each sentence?

1) If you have called me tomorrow I will tell you everything.(I will tell you everything after you hang up the phone)

2) If you call me tomorrow I will tell you everything. (I will tell you everything on the phone)

That's a fair interpretation, but with this situation of calling and telling, the tenses themselves do not make it absolutely clear. We could, for example, say:

1. If you call me in the morning, I will tell you in the afternoon.
2. If you have called me in the morning, I will tell y0u in the afternoon.

#1 might suggest that I will tell you, if it happens that you have called me earlier, while #2 might suggest that I will tell you provided that you call me earlier. However, note my use of 'might suggest'. I said in an earlier post, "There is a difference, though it may not be significant"; perhaps I should have said, "Some people might feel there is a difference"
