LOL Tom.
When I have made the big decision to try and come up with something new on guitar, I have the recorder playing as sort of scat along as I play and simply mumble what chord I have changed to when, (and if) I do so I can remember where I went later and write them down into their correct bars, when (and if) I put the guitar down.
No matter how badly I play guitar, it has always been a relaxing thing for me to do, so it is all good and creative as I see it.
