I'd like to focus on the instrument rather than singing along with the instrument. Not sure if Rock Lobster by the B-52's would be too difficult of an undertaking for a beginner.
Welcome
@Kyle Poston!!! I'm not that far from a beginner myself, and I'll tell you the hardest question to answer, and the answer can change a lot depending on the context, but here's the question: What's a song?
You've started to answer that by saying that you're less interested in singing. Great start! So what do you want to play? Are you interested in playing the notes that the singer would be singing, along with the "guitar" parts at the same time? That's a thing called chord melody mentioned above. It's super popular, but also complicated.
So let's back up, and start with the intro to Rock Lobster.
(Before that, a detour. LOL This song landed in my freshman year of college, and changed EVERYTHING. You could argue, and I would, that The B-52s were the first "college radio" band -- before MTV, they blew like wildfire across the nation as college radio stations like the one I worked at were passing the news among themselves as the thing you HAVE to hear. There was no internet of course, so we were WRITING LETTERS, and picking up the phone and calling our friends at other colleges. We were losing our MINDS over this!
The first project I did in my radio-TV-film production course was centered around Rock Lobster, which most of the class, including the professor, hadn't yet heard, and the room practically exploded with fevered discussion when I played a few bars of it. It felt like standing at ground zero, and I've never forgotten it.)
One way to play the intro is just the notes. Easy enough! A BUNCH of tutorials for that. Here's one, barely over a minute long.
But me, that's never going to be what I want to do. I hate one note solos, BUT THAT'S ME. Like whatever you like, and apologize for nothing. LOL So, given that I'd personally always rather play chords, here's another tutorial, under two minutes, but for ME, dang near a bullseye.
Not as obviously beginner friendly, but if that's the mountain you want to climb, go for it!
Once you want to climb
all the way up the mountain, consider this entry from UU's own
@UkeFoote, who I think is an absolute genius.
He's answering part of the rest of the question, which is, "What do you wanna do with all the stuff that's not guitar????" In Brian's case, he whistles. And yeah, he sings it really, really well, too! With lots of layers of vocals that he recorded himself. And you can see what he's playing very clearly, and answering that at THIS level, mmmm, not exactly a first song. Unless you want it badly enough, in which case, go for it!
I'm not saying any of this to be discouraging. Quite the contrary! I'm saying that there are a gazillion ways to do everything. Some are easier, some harder, but it's all up to YOU. What do you want this to sound like in the end? Are you playing with a vocalist? Are you wanting to play along with the record? Do you want to play the whistling parts with your ukulele, can you whistle, or would you rather use a kazoo? (Which I think would sound awesome for this song, btw.) Nobody can answer any of this for you.
But if you can give us some answers to some of these questions, we may be able to help point you in a more helpful direction.
