“Requiem”
Music- Vanity Fare “Hitchin’ a Ride” and “Early in the Morning”
Left Banke “Walk Away Renee” and “Pretty Ballerina”
Naked Eyes “Always Something There…” and “Promises Promises”
Maxine Nigtingale “Lead Me On” and “Right Back Where we Started From”
Silver Convention “Fly Robin Fly” and “Get Up and Boogie”
A Taste of Honey “Sukiyaki” and “Boogie Oogie Oogie”
Ian Matthews “Woodstock” (with Matthews Southern Comfoft) and “Shake It”
Champaign “Try Again” and “How 'Bout Us”
Foundations “Build Me Up Buttercup” and “Baby Now That I’ve Found You”
and one that annoys me is when the have “Ice Ice Baby” on all the one hit wonder shows. Granted, his career as a whole was forgettable, but his version of “Play That Funky Music” peaked at **#4 ** on the pop charts. How can you call a guy a one hit wonder when he had another top 5 hit? One hit wonders by definition aren’t “we only remember one song of yours” they are “you only had one hit”- there are dozens of artists who had many hits, but one is more memorable.
“Never My Love”
Along Comes Mary
And cult film Death Race 2000, as Big Joe Viterbo.

Not sure here, but I have a feeling that like some disco groups (and bubblegum bands), the Silver Convention was a studio band, put together by a producer, and using whatever musicians and vocalists happened to be handy for each recording. If that is the case and the band had shifting personnel, should we include it?
'Course, if we can, then I’ll offer another studio band, the Archies, who did “Sugar, Sugar” and “Bang Shang-a-Lang.”
Can we agree what we’re talking about when we say “Two-hit” wonders? Is it just Two memorable moments/roles/songs? Two-hit movies?
As an example:
I think Stallone is pretty much a Two-hit wonder with Rocky Balboa/John Rambo being the two roles for which he will be remembered. That he was in Judge Dredd or Lords of the Flatbush or any other movie that made more than three dollars would be considered irrelevant, because those aren’t the roles he’ll be remembered for.
Harrison Ford: is probably a three or four hit wonder Han Solo/Indiana Jones/Jack Ryan/(Maybe) Dr. Richard Kimbell. That he was in Working Girl, Sabrina, American Grafitti, or even Witness is pretty irrelevant, because those are the “also-ran roles” not the signature roles.
Are we talking signature roles or hit movies? My interpretation of the original post is “Signature Roles” not “Hit Movies” Songs are an easy category, I don’t think there’s any confusion about that since they are ranked by top 5 or 10 (not 40), but we should determine a cut-off point for them.
Just looking for some clarity rather than people saying Andrew Dice Clay: Ford Fairlane and he did some porn, oh, he was in “Casual Sex” with Lea Thompson and Victoria Jackson too. (Well, I’m sorry, he’s a one hit wonder with “Ford Fairlane” being his signature role–unless you want to count his ADC personna).
How about Pierce Brosnan - James Bond and Remington Steele
Ironically, I’ve loved him in pretty much everything else he’s ever done, but really disliked him in those two roles. Go figure.
There were quite a few like that. I’m thinking of the band Lime- “Do You Want to Love Tonight” and “Angel Eyes”
I think they had different people that actually toured.
Whoops - hit reply too soon. I was going to add in the same vein, Roger Moore for James Bond and Simon Templar
Spoons, I agree it’s doubtful that the same studio musicians played on both hits attributed to Silver Convention, and possible that the three girls who fronted the “band” didn’t contribute anything- not that either hit had any real vocals- more like a repeat of the song title. Both could techincally be classified as instrumentals I think. But alas, if were are going by the name on the label of the 45, they count 
There are a lot of 60’s/70’s studio bands who didn’t exist, but the label formed a band with musicians who didn’t appear on the record and toured after their song became big (Steam, The Cuff Links, plus all of the Tony Burrows “groups”- White Plains, Edison Lighthouse, etc.), I don’t think any got a second hit, though.
Archies: Jingle Jangle
Peter Scolari is really only remembered from Bosum Buddies and Newhart.
And since a commercial for Bonanza was just on, I can’t recall any roles overshadowing Lorne Greene except for Pa Cartwright and the captain in the original Battlestar Gallactica. Nor Michael Landon except for Little Joe and the father in Little House on the Prarie.

A Salty Dog- did not chart
Left Banke-
Walk Away Renee #5
Pretty Ballerina #15
Desiree’ #98
Bryant Hotel- did not chart
To me, it’s a question of dropoff after the first two items. Harrison Ford was good in the Jack Ryan movies and in The Fugitive, but those roles are just orders of magnitude less prominent, less loved, and less iconically associated with him than Han Solo and Indiana Jones. Same thing goes for Julie Andrews. That’s what I’m getting at, at least wrt to actors. It would be QUITE hard to find an actor who had two enormous hits and absolutely nothing else period, if only because actors who make a huge hit generally then get cast in other movies, even if they all suck.
(I guess you could also have a variant of this question addressing specific groups… among youngish nerds, Ian McKellan is Magneto and Gandalf and… ummm…)
What about the angel in “Highway to Heaven”?
Well, right off the top of my head: “Never, My Love” and “Goodbye, Columbus”. Oh, and there was a little ditty (not one of my favorites) called “Along Comes Mary”.
