20 Greatest Hits does indeed offer most of Three Dog Night's definitive songs, including classics like "One," "Easy to Be Hard," "Mama Told Me Not to Come," and "Joy to the World." Though there's not much to differentiate this British compilation from domestic anthologies like The Best of Three Dog Night, 20 Greatest Hits is a solid overview of Three Dog Night's best work. ~ Heather Phares, All Music Guide
