I think River Deep Mountain High may be one of the greatest pop songs recorded.
A credit to Phil Spector's legacy, although many believe that this is the song that set him on his decent into self destruction. He thought that the song was his greatest achievement, and had high hopes for it. The song topped billboard charts at #88 (European #3). Ike (who had been paid off so he would have no say in the original production of the song) later re-produced it so that it would work better for the duo.
This is a bit of a wobbly live version, but the vocals are spot on.
