I have two after reading some of the other entries. Same songs, different misheard lyrics. First is the song by Neil Diamond called "Forever in Blue Jeans". I thought it was "A River in Blue Jeans". 'Nuff said...
The second is Huey Lewis' "I Want a New Drug". In that song he says, "...the old boy may be barely breathing..." I used to think he was saying, "the oboe may be barely breathing."
A childhood belief about misheard lyrics

others believed things like this
- The song "Reverend Blue Jeans" turned out to be "Forever in Blue Jeans." Who would have believed that?— music lover
- I used to think that neil diamond was singing about the reverend blue jeansAnon
- I used to think that the Huey Lewis and the News song "I Want a New Drug" went "I Want a New Truck".— Chloe
- You know the eifel65 song "Im blue da be da ba di"
I thought he said "I'm blue I'm in need of a guy"— Anna - that song that goes *bring me a higher love*
i thought it said *breathing in iron lung*— oi - In 'Call Me Maybe', I misheard 'Ripped jeans skin' as 'Rich cheese skin'. — Carly Rae Cheddar
