So this doesn't happen too often :-).
On Friday, I got some speaker stands from Musician's Friend from their stupid deal of the day. I set them up in my practice area and decided to give them a spin. So I played some songs to jam along with. One of them was Comfortably Numb. Over 10 years ago, my teacher taught me the solos and I never really mastered them, though I run through them to this day.
So I'm playing along last night and I nail it! A second time...and I nail it! Today, I play along again and nail them!
The piece I was missing...slow down! Yes, SLOW DOWN! I always thought I wasn't playing fast enough, but it turned out I had to slow it down.
What I think has happened is that by learning other songs in the meantime on Guitar Tricks (Life in the Fast Lane and Carry on my Wayward Son in particular) my sense of what is fast has changed. The comfortably numb solos seem slow to me now.
Pretty strange, but I have to say it is a pretty large accomplishment for me. Finally I can say I can play those solos in total!!
