In 1974, McVie reluctantly agreed to move with the rest of Fleetwood Mac to the United States. Within a year Stevie Nicks and Lindsey Buckingham of Buckingham Nicks joined the band, giving it an added dimension. Their first album together, 1975's "Fleetwood Mac", had several hit songs, with McVie's "Over My Head" and "Say You Love Me", both reaching Billboard's top-20 singles chart. It was "Over My Head" which first put Fleetwood Mac on American radio and into the national Top 20.
