Written by Doyle Bramhall and SRV. These two were friends who grew up together and wrote this song based on their lives, as they went there separate ways as they grew older and ultimately came back together in later years. A reminder to us all to live life by the drop, to the last drop. Not wasting a bit of time that we have, some less than others, and all of it is precious. Don't take it for granted, and soak it up for all it's worth.
