Although the record lists the writers as Yellen, Ager and Sullivan, earlier publications credited Harry Ruskin for the lyrics, with music by Harry Sullivan.
I may be wrong but I think you're wonderful
I may be wrong but I think you're swell
I like your style, say, I think it's marvellous
I'm always wrong, so how can I tell?
All of my shirts are unsightly
All of my ties are a crime
If, dear, in you I've picked rightly
It's the very first time
You came along, say, I think you're wonderful
I think you're grand but I may be wrong
I May Be Wrong was written by Henry Sullivan & Jack Yellen & Milton Ager.
Jack-hylton released I May Be Wrong on Fri Jan 03 1930.
