Narrative:

Day four of seven; leg three of five for today. Being slightly tired and after not seeing a cloud in the sky for the last two months. We somehow failed to get landing clearance from tower when landing today while doing the back course to 27L. I was pilot flying; I and my copilot never recall getting passed on to tower from approach control. We never caught it. I believe we got caught up in the unusual situation of shooting an approach let alone a back course; which we rarely do. Upon landing roll all seamed normal until we never received taxi clearance off the active from tower. After turning off at a normal/safe taxiway we noticed we were not on tower frequency nor were both landing lights in the normal landing position. We were still on approach frequency. We then contacted ground control and taxied to the FBO and deplaned our passenger in a normal fashion. Maybe ten minutes later; after discussing with my flying partner; I called tower on the phone and spoke with him on our situation. The tower was glad we called; and said no further action was required.
