Penguin is the seventh studio album by British-American rock band Fleetwood Mac, released in March 1973.

Weston was well known for playing slide guitar and had known the band from his touring period with Long John Baldry.

The album's artwork was painted by Chris Moore and the gatefold photo was shot on location at Ludshott Common and Waggoners Wells in Hampshire, according to Dave Walker in an online Q&A interview.

The subsequent tour seemed to go well, and Penguin was the highest charting Fleetwood Mac album in the US at the time, clawing its way into the Top 50.

However, during the recording of their next album, Mystery to Me, it was mutually agreed upon that Walker's vocal style and attitude "did not fit in" with Fleetwood Mac and by June 1973 he had left.
