The "hook" feature of Paul's no. 1 Flying V during the Spirit of '76 Tour is such an easy-to-miss detail, much like the hairline crack in the mirror pickguard, that I think it requires a small section of its own. Truth be told, this is a detail I had completely missed myself, both the hook itself and its use, until it was pointed out to me by Ros Radley of
MAGIC - KISS Kronicles 1973 to 1983. Case in point, I'm willing to bet that most people perusing this site didn't see the hook in the photo on the right when it was used to illustrate the hairline crack in the mirror pickguard.
The "hook" in question is an Omega-shaped metal hook attached to the upper part of the body a little below the neck. It's not visible in any photos from the European tour earlier in the year and is doesn't appear in the photo shoot on
June 24. In other words, this is a feature that was added specifically for the Spirit of '76 Tour and although it might have been added before the tour the first photo that shows it that I've been able to find is from Toledo, OH on June 31 as shown in the two pics on the right. It is however, as mentioned below, apparent in Jersey City, NJ on July 10. (I've taken the liberty of circling the hook in all the pics since it's so hard to find.)
Now, this doesn't necessarily mean anything since the hook is mostly "invisible" due to Paul's costume at the time; the rhinestone-covered crotch of Paul's Destroyer costume tends to make the hook disappear in photos taken directly from the front as
seen here, and since it is in use early in the tour it's very likely that it's present at the very start as well.
