I used to could would be a cool closer.
it's a matter of taste, but this kind of song sounds album opener to me, not a closer.
I always prefered clam songs for albums closers : BIA, Follow me home, are we in trouble now, one more matinee, old pigweed, etc...
in the case of Privateering, I would see Radio city sereande as the perfect closer, or better: follow the gibbon with his never ending outro
but I alawys find a bit strange to end an album on a uptempo song. what's why songs like CBC or IUTC fit more in beginning on the album imho
as for the album, I like it, but not very found of the blues tracks. If I want listen to "white" blues, I surely don't go for MK, but rather to SRV, EC, Stones, ABB, Derek Trucks, Winter, Gallagher, ZZ Top, etc...
my favs are : submariner, go love, bluebird, blood and water, serenade, YTC, IUTC, occupation blues. Not much found of rebud tree. for this kind of typical stratish clean sound, I prefer beachcombing for example
what I don't like on the Privateering album is the bass sound : several songs have saturated bass, like Go love for example. Very strange for sound quality obssessed guys like GF and MK
