By 1976, Queen were back in the studio recording A Day at the Races, which is often regarded as a sequel album to A Night at the Opera. It again borrowed the name of a Marx Brothers movie, and its cover was similar to that of A Night at the Opera, a variation on the same Queen Crest. The most recognisable of the Marx Brothers, Groucho Marx, invited Queen to visit him in his Los Angeles home in March 1977; there the band thanked him in person, and performed "'39" a cappella. Musically, A Day at the Races was by both fans' and critics' standards a strong effort, reaching number one in the UK and Japan, and number five in the US. The major hit on the album was "Somebody to Love", a gospel-inspired song in which Mercury, May, and Taylor multi-tracked their voices to create a 100-voice gospel choir. The song went to number two in the UK, and number thirteen in the US. The album also featured one of the band's heaviest songs, May's "<answer>Tie Your Mother Down</answer>", which became a staple of their live shows.
