Does "Best forgotten Ringo song" mean the song of his that is best forgotten?
I'm going to assume you meant the opposite!
I really like "You're sixteen" (I'm not sure that's the real name, it has the line "Peaches and Cream" in there) ,
and I really like "Only You"!
These were both AM radio hits when I was in high school, I guess that's why I like them. Since then I've heard the originals, and I guess they might be considered better, but I like Ringo's versions best!
