Anyone wanting to practise Coltrane subs on II-V-Is should load up Countdown.

The tune is Trane's reharm of Tune Up (which I prefer to credit to Eddie Vinson, rather than Miles).

The original key is Bb, and the tune uses II-V-Is in D, C and Bb. Transpose to Db, E and G, and you'll have practised Trane subs in all keys.
