Famous to some means nothing to others.
Above some level of skill and talent is an “irrational” feeling. An emotional connection, a nostalgic longing. To the newcomer, with no history, it’s not all that impressive. But to one with history, it’s everything you remembered it to be and more.
That’s why you should perform for those with history. Because it’s a zero to one difference between those who get it and those who don’t. A certain crowd will show up with a confused look and expect you to prove yourself. The other crowd will expect an reinforcement of why they already love you.
Famous is always subjective. The more important question is “famous to who?”
