Cover art for Signs lyrics by Five Man Electrical Band

The song's not really about signs, as such, the signs just happen to be the method of which it's being carried.

Specifically, it's more focused on restrictions, rules, subdividing, and essentially, a culture based upon splitting people apart, with an endless emphasis on whot yeu CAN'T do.

How many signs have positive messages? Other than ones held at rallies or marches, generally few, if any. Almost all signs are things which warn, things which note restrictions, or things which block access.

Is it a 'hippie' thing to be frustrated with such? To some degree, yes. On the other hand, should we really be so complacent with a culture which is founded on restrictions and subdividing groups apart?

That's pretty much the point that's trying to be made; the 'signs' are just a focal point to vent that frustration at.
