I'm not quite sure why you'd do that. The tempo is part of the
music. The tune titles that you want to include are not. But you can
add spaces to the beginnings of strings to avoid collisions.

A lot in there. Your OP didn't have automation specified. Most people
drop into scheme for that, don't they?
Why not push the rehearsal mark left if you want loads of text to the right?
I don't get the bit about notes in a MMR. Isn't that a contradiction?

Well, that's a relief. BTW you can have multiple marks. My example had
one \tempo and the rest were marks.

I haven't yet seen an example of what you want, not anything that
you've produced in the dim and distant past that you barely remember.

Again, isn't that why people use scheme. Then you can see if a given
moment has a note or not, and choose your markup appropriately.
LP never looks very automatic to me. It doesn't even have an "if"
construction to make a decision.

Anyway, I made mr jones into a nonsensical "\tempo". The rehearsal
letter now appears above it of course. I stuck a note in before the
MMR for some reason though nothing is anchored to it; everything but
mr jones is a \mark. I'm just doodling—not sure why I bothered.

Cheers,
David.
