A question
I've noticed on my Concorde that when I sit up and let go of the handlebar, the front wheel is wobbling.
What may that indicate? Could it be a headset issue, the fork or what?

As Dr Archie Campbell would say " well don't do that".

Make sure the front wheel is properly inserted in the dropouts.
Put the bike on the ground, and release the frt QR, then tighten it again.

Could be a lot of things, from a tire that's not seated evenly or slight bulge on one side to the more obscure.
Look over the basics closely first.

first check to see if wheel correctly dished. if you do not have a dishing gauge you can try reversing the wheel in the fork to see if it lines up in the same spot.

if wheel correctly dished then problem likely in fork. fork needs to be checked in an alignment gauge. it must be withdrawn from frame for this procedure.

also check alignment of fork tips with Campag tool or similar.

it can happen that a fork is constructed with unequal effective blade length. if this is found the long blade must be shortened by deepening the axle slot in its fork tip.

Any LBS should be able to tell if the fork/drop outs are bent in a matter of minutes.

I've been meaning to ask about this as well. I just read Sheldon Brown's writeup on this. So can shimmying still happen even after checking if everything is fine and in alignment on the bike? This only happens on my bike when I ride with no hands at high speeds on flatland. When I'm on the bars, it's straight as a whistle.

Much of the above might be it. If you have another set of wheels that would fit, try those one at a time and do a test of the permutations. Then go to the more primal causes such as the fork, frame and or headset.
Of course, every time I ride with my son and I ride "no hands" he warns me I might crash....
