Here's a tune originally written by Wilbert Harrison (he who was the first to record "Kansas City") under the title "Let's Stick Together", but given a new title and lyrics later by the same Wilbert. Canned Heat had a big hit in 1970 covering it very nicely. Two Alonzos and two Larivee 12-strings, one tuned high and one tuned low. But the one tuned lower is actually spatially higher...well...you'll see.
As for the message, well, I can't think of a more timely time for it, though some might call it a naive pipe dream. Maybe not, though. Can't hurt to wish for it.
