Cologne

Searching for something I don't get-
 It's prodding me
 ♪
 In the place where Stone and Steel met-
 Their battle's shown on me
 Bet tourbillon won't serve me wrong-
 Still won't help my French-
 ♪
 So I keep marching on to meet cologne
 And dissolve this stress
 And I see
 Towers; the turrets of all the churches
 But one is best
 In currents
 Through nervous and anxious surges-
 Only one is best!
 ♪
 So old and regal
 Can't find this aid-
 And my storming spirit
 Seems to abate!
 Cologne, you've failed me
 In brown and brazen-
 I'm barely grazing
