Answer by taking a quote from the following article:

Huey Lewis and the News is an American pop rock band based in San Francisco, California. They had a run of hit singles during the 1980s and early 1990s, eventually achieving 19 top ten singles across the Billboard Hot 100, Adult Contemporary, and Mainstream Rock charts. Their most successful album, Sports, was released in 1983. The album, along with its videos being featured on MTV, catapulted the group to worldwide fame.

The band's lineup has changed moderately since its heyday. Bassist Mario Cipollina left the band in 1995, and was replaced by John Pierce. The Tower of Power, which often served as the band's touring horn section in the 1980s, ceased their work with the band in 1994. Horn players Marvin McFadden, Ron Stallings and Rob Sudduth joined the group in their place as "The Sports Section." In 2001, Chris Hayes retired to spend more time with his family after performing on the album Plan B. Stef Burns became Hayes' successor. Guitarist James Harrah has filled in for Burns occasionally. On April 13, 2009, touring saxophonist Ron Stallings died from multiple myeloma.  In 2000, Lewis co-starred with Gwyneth Paltrow in the film Duets, in which the band performed their hit cover of "Cruisin'". In 2001, the News released their first album in seven years, Plan B, on Jive Records. It only briefly made the charts, while the lead single, "Let Her Go & Start Over," became a minor adult contemporary hit. The band continues to tour regularly, playing around 70 dates a year. In December 2004, Huey Lewis and the News recorded the live album, Live at 25, at the Sierra Nevada Brewing Company in Chico, California, which celebrated the band's 25th anniversary. In 2008, they recorded the theme song to the action-comedy film Pineapple Express. The song is played over the end credits of the film and appears on the film's soundtrack album.  The band returned to the studio in 2010, recording their first album of new material in nearly a decade. The album, entitled Soulsville, is a Stax Records tribute album recorded at the legendary Ardent Studios.  In 2013, a new song called "While We're Young" was played at concerts. The song is featured in the animated film, Animal Crackers. The band is expected to release a new album sometime in 2018.
