Are you confusing the Quakers and the Shakers? (or the Amish or … who knows what oddball Protestant sect you’re thinking of.)
I am unaware of any strictures against music amongst the Society of Friends.
Steve Martin plays the banjo. What does that make him?

A strummer and a picker.
I have Quaker ministers in the family some generations ago (ca. early/mid 1800’s). More recently, the family had morphed into general fundamentalists, and their particular brand of fund prohibits music outside of hymns, folk or classical music (blues & jazz are the Devil’s work, along with all dancing). I just assumed their predecessors were more strict; perhaps the opposite is true.
Twas a time when it seemed that way, thanks to the Borscht Belt. And thanks to those guys goyim like Alda and me picked up enough Yiddish to make it something like Spanish is today, America’s second language that nearly everybody knows some of.
Different branches. I’m a Philly Quaker – silent meeting, super liberal, no clergy. (No music in services, but no objection to it otherwise. 
)
BTW, the Shakers are/were very musical. Very into writing & performing hymns, marches and dance music (I mean that’s why they’re called Shakers, yo).
Nothing else to add, just thought I’d throw that in. :
We seem to be getting somewhat off-topic here. And, yeah, I know I started it, but we should end this hijack.
What was the topic again? What ethnic groups are known for their banjo-playing proclivities?
“You mean I’m going to stay this color?”

Every interview I’ve heard him give he is introduced with the pronunciation you give, and he’s never corrected anyone. How else would you pronounce it?
Actually that’s a good question. We Jewish types pronounce it LEE-veye, and I’m pretty sure so do the old school Christians or Mormons who’d be likely to use the name. Does someone out there pronounce it “levvy”?
ETA: Wait, maybe dropzone is thinking of the name Levin, which is either pronounced le-VIHN or LEH-vin depending if you’re [del]pretentious[/del] more of a Francophile; or possibly Levine, which can be le-VYNE or le-VEEN or even LEH-vin?
I was surprised to learn that Richard Nixon was a Quaker.
I was always under the impression that Billy Joel was an Catholic Italian-American (probably due to songs like “Only the Good Die Young” and “Scenes From an Italian Restaurant”). Several years ago, I saw his picture on the cover of a cookbook dedicated to recipes from Jewish-Americans. Imagine my surprise.

I go to a Friends church - we have a banjo-playing member.
EDIT: We also have music in service, a leading pastor & all the standard service things as most protestant churches. We don’t do immersion or sprinkled baptisms (you’re baptized by the hold spirit, not by water) and that’s about all I’ve seen that’s kinda weird.
In general, I think of it as middle-of-the-road protestant.
Good one! I can undertand “Scenes” making you think Italian/Catholic, and maybe “Moving Out” since the lead dude is named Tony. OTOH, isn’t the point of “Only the Good Die Young” that our hero is looking from the outside of the whole Catholic thing (“You Catholic girls start much too late…”) and sort of teasing or mocking it?
Before I knew his name, I thought Tony Shaloub was Italian (c.f. Wings and Big Night).
Well, sure, if you go to a “church” rather than a meeting. 
ETA: that was directed at Belrix; choie snuck in while I was posting.
I’d always assumed (correctly, as it turns out) that he was of some sort of Middle Eastern descent. What did surprise me was to learn that he was born and raised in my home town of Green Bay. He hides that northern Wisconsin accent quite well.
Heck, wasn’t the LEE-veye of “jeans” fame Jewish?
So Wikipedia says, though it also says that Levi wasn’t his birth name:
Yeah, but in both instances they spent a lot of time in their adopted homelands. Probably more true of Bob Hope than Mel, who if I’m not mistaken moved to Australia as a teenager.
