McCartney was the first solo album by Paul McCartney and was released in 1970.
McCartney shot to #1 in the U.S. for three weeks, eventually going double platinum.
In the U.K., it was only denied the top spot by the highest-selling album of 1970 (and one of the all-time top-selling albums) Simon and Garfunkel's Bridge Over Troubled Water, which stayed at #1 for 41 (non-consecutive) weeks.
