All done but two puzzling answers.
38d Beer. Linger over s
econd half (5).
I'm assuming the line-break in "second" in the clue is accidental but I've included it anyway just in case.
Crossing letters L_G_R. Has to be Lager but can't see why.
69d City partnered with Detroit.
_D_L_I_E
Answer is Adelaide (Australian cities are required for the theme).
Can't find a straight or cryptic link between the two. Any thoughts?
