I was looking at some old IFR Refreshers tonight, and found the IFR Quiz
from September 2002. See http://204.108.4.16/d-tpp/0503/00282I2C.PDF.

Question #4 asks how to identify TANDS, and the answer they give is "BNA
DME and Livingston's R-270". Isn't that kind of nuts? The DME arc is
almost tangent to the LVT R-270, and would thus give an extremely sloppy
fix. The only rational ways in my mind to identify TANDS would be to cross
the BNA R-106 with the LVT R-270, or the BNA R-106, DNA 24.7 DME.

Is there something I'm missing here?

Seems to me you're missing something. ;-)

The sloppy tanget to the BNA DME would exist only if you were flying along the
LVT 270 radial. But, you're not. In the context of that approach chart you
flew the missed approach northbound on the BNA 016 radial until either BNA 24.7
DME or until crossing the LVT 270 radial northbound tracking BNA 016 radial.
Then, you enter the hold flying on-course southbound on the BNA 016 back to
TANDS.

So, what's sloppy about the BNA 24.7 DME fix when holding north of TANDS on the
BNA 016 radial (i.e., as the hold is charted)?

TANDS is authorized only for use along V-49, which is the BNA 016 radial at
that location. It is not authorized for flight along the LVT 270 radial unless
ATC were to give you an impromtu clearance to track the LVT 270 radial.

It's a long ways from LVT to TANDS (67.4 miles) so that is a pretty sloppy fix,
compared to the BNA R-016/24.7 DME. Also, according to the NACO L-21 Lo En
Route Chart, the MRA is 3,000, which makes it a pretty marginal fix using the
LVT 270 radial. They had to chart it that way, though, to keep the procedure
from requiring DME.
