Problem: The Wallflowers are an American rock band formed in Los Angeles in 1989 by singer-songwriter Jakob Dylan and guitarist Tobi Miller. The band has gone through a number of personnel changes but has remained centered on Dylan. After releasing their eponymous debut album in 1992, the Wallflowers released what would become their best-known and highest-selling album, Bringing Down the Horse in 1996, which featured songs such as "One Headlight" and "6th Avenue Heartache". They went on to release an additional three albums before going on a seven-year hiatus, beginning in 2006.

In 2001, Jakob Dylan began writing for the Wallflowers' fourth album, Red Letter Days. Later that year while on tour with John Mellencamp, the band began recording using portable equipment. Some recording was also done at keyboardist Rami Jaffee's house. Once the band was finished touring for the year they began recording the bulk of the new record at Jackson Browne's studio in Santa Monica. By the time the Wallflowers had gotten into Browne's studio, Michael Ward had left the band, leaving them without a lead guitarist for the recording process. Dylan took on much of the lead guitar duties with Mike McCready, Rusty Anderson and Val McCallum also contributing on guitar. Moe Z M.D., who had been touring with Mellencamp, contributed additional percussion and background vocals to the album.Red Letter Days was produced by founding Wallflowers member Tobi Miller along with Bill Appleberry. Recording continued through the new year and was completed on April 12, 2002. The album was mixed by Tom Lord-Alge, who had mixed the band's previous two albums. Mixing was completed on May 15, 2002. While the Wallflowers were working on Red Letter Days, they recorded a cover of the Beatles' 1965 song "I'm Looking Through You" for the soundtrack to the 2001 film I Am Sam. The soundtrack was released on January 8, 2002. The first single from the Red Letter Days, "When You're On Top," was released to radio on August 16, 2002. A music video directed by Marc Webb followed. After a few false starts, Red Letter Days was released on November 5, 2002. The album was met with mixed to positive reviews. Many critics noted the harder rock sound and catchy melodies used throughout the album. Commercial performance was relatively mixed as well, peaking at No.32 on the Billboard 200. Around the time of Red Letter Days' release the Wallflowers embarked on a monthlong U.S. tour stretching into early December. After another U.S. tour in January 2003, the Wallflowers toured in several European countries in February including Spain, Italy, Germany and Great Britain. After this tour, the Wallflowers' drummer since 1995, Mario Calire announced he was parting ways with the band. In 2003, the Wallflowers were featured on the soundtrack for the film American Wedding. The band recorded a cover of Van Morrison's 1970 song "Into the Mystic". The film's music department weren't able to secure the licensing rights to use Morrison's version so they enlisted the Wallflowers to cover the song. Both versions of the song were, however, featured in the film.

Question:
Hans Lundgren was born on 3 November 1957 in Spanga, the son of Sigrid Birgitta (nee Tjerneld), a language teacher, and Karl Johan Hugo Lundgren, an engineer and economist for the Swedish government. He lived in Spanga until the age of 13, when he moved to his grandparents' home in Nyland, Angermanland. Some sources wrongly state 1959 as his year of birth, but Lundgren himself has confirmed it to be 1957. He has two sisters and an older brother; he was raised in the Lutheran church.
Although Lundgren has never competed as a professional bodybuilder, he has been closely associated with bodybuilding and fitness since his role as Drago in the mid-1980s. Bodybuilding.com said, "Looking like a man in his 30s rather than his 50s, Lundgren is the poster boy of precise nutrition, supplementation and exercise application that he has practiced for over 35 years." In an interview with them, he claimed to often train up to six days a week, usually one-hour sessions completed in the morning, saying that "it's just one hour a day, and then you can enjoy the other 23 hours". Although he had begun lifting weights as a teenager, he cites co-star Sylvester Stallone as the man who got him into serious bodybuilding for a period in the 1980s after he arrived in the U.S. Stallone had a lasting influence on his fitness regime and diet, ensuring that he ate a much higher percentage of protein and split his food intake between five or six smaller meals a day. Lundgren has professed never to have been "super strong", saying that, "I'm too tall and my arms are long. I think back then [Rocky IV] I was working with around 300 pounds on the bench and squat." In a January 2011 interview with GQ he announced he is working on releasing his own range of vitamins and supplements. He wrote an autobiographical fitness book, Train Like an Action Hero: Be Fit Forever, published in Sweden (by Bonnier Fakta) on 9 August 2011, offering tips he learned over the years to work out in various situations (with a busy schedule and a lot of traveling). On 9 September 2014, Lundgren published Dolph Lundgren: Train Like an Action Hero: Be Fit Forever, a book which contains a detailed account of his earlier life and troubles. He cites a better quality of life as having inspired him to maintain his physical fitness. When in Los Angeles he trains at the Equinox Gym in Westwood and when at home in Marbella, Spain, he trains at the Qi Sport Gym in Puerto Banus. Dolph does, however, also like to spar and practice his karate in the gym to keep in top shape aside from weight lifting. He cites dead lifting and squats as the best exercises for muscle building. Lundgren is not a heavy drinker, but has professed on many occasions to being fond of tequila and cocktails, citing his knowledge in chemical engineering as "making really good drinks".
