Well let's start with the cut and dry one - for a late night set, yes!! The whole process involves honing in on a specific, perfectly repeatable set with no surprises.
For anything else… it's complicated. Because, as always, we're all our own monsters.
If you'd like to do the same set, here's some things to remember:
If people like your jokes, they like hearing them more than once! There's some jokes that are 7 or 10 years old that I still laugh at when they just pop into my head, nevermind hearing them onstage.
You got here for a reason, you don't necessarily need to worry about proving your versatility and range! This obviously varies by opportunity but I'm pretty sure there's no one who got a Netflix new faces audition off of the only 5 they have. It's assumed you have the ability to do 20 or an hour, otherwise your 5-7 wouldn't be this good!
And certainly don't do a different set if it isn't as strong as the first one!
On the other hand, arguments for doing a different set are:
You'll be more excited about it! We all know even sliding a couple new jokes into your regular set can energize the whole thing. Don't go new new but if you have another strong set that you'll have fun with, go for it!
There are some circumstances where you'll benefit from showing your range. A lot of competitions and “younger” festivals will have industry judging or watching who have no context for you. We’re not dummies, but it’s always nice to reinforce a positive impression with an even more positive one!
