Sore fingers just mentioned that it's good to revisit. Honestly, it's good to revisit anything that helps you improve your playing.

However, it's not required. Go back if you think it helps you with something. Even if it's just a warm up. Don't go back to something that you learned as a beginner if it does not enhance your skill or help you in some way.

Truth is, the second song I'd ever learned was Zep's Black Dog and it remains a song that is never a natural song for me to play. So I still warm up on it often. I've been playing it for nearly 40 years but I still have to pay attention when I do.
