"Might one ask how to access them?"
There is a browseable version of the VMP tunes available at http://richardrobinson.tunebook.org.uk/collection/101
It doesn't include the new Sands material yet (my watch-for-changes script only told me about it a couple of days ago), but it will before long, next day or two. (John Adams - assuming that your agreement it's okay to put up a copy extends to these, too ? Which I will assume unless told otherwise ...)
