Benny was born in Chicago, Illinois, and grew up in nearby Waukegan, Illinois. He was the son of Meyer Kubelsky and Emma Sachs Kubelsky. His parents were Jewish. Meyer was a saloon owner and later a haberdasher who had emigrated to America from Poland.
Benny's comic persona changed over the course of his career. At some point he developed a miserly persona. This stage character was everything that Jack Benny was not: cheap, petty, vain and self-congratulatory. His comic rendering of these traits was the linchpin to the success of his show. Benny set himself up as comedic foil, allowing his supporting characters to draw laughs at the expense of his own flaws. With his humanism and vulnerability in an era where few male characters were allowed such character traits, Benny made what could have been unlikable into an everyman character. Benny said: "I don't care who gets the laughs on my show, as long as the show is funny." Benny felt he got the credit or blame either way, not the actor saying the lines, so there was emphasis on the comedic bottom line. This attitude reached its apogee in a broadcast structured as a Hollywood bus tour of the stars' homes. Each "stop" on the tour was at a house belonging to one of the show's supporting cast, who would then have a scene which included jokes about the absent Benny. Not until the final moments of the program did the bus arrive at Jack Benny's house, at which point the listening audience heard Benny's only line of the episode: "Driver, here's where I get off." Few stars possessed the combination of daring, humility and comic timing to commit to such an extended payoff. Mary Livingstone, his wife, was a supporting character, as his wisecracking and not especially deferential female friend. She was not quite his girlfriend, since Benny would often try to date movie stars like Barbara Stanwyck, and occasionally had stage girlfriends, such as "Gladys Zybisco". Don Wilson, the rotund announcer, also appeared on the show. He also announced for Fanny Brice's hit Baby Snooks. Bandleader Phil Harris appeared as a jive talking, alcoholic philanderer whose repartee was profoundly risque for its time. Boy tenor Dennis Day appeared as a sheltered, naive youth who often got the better of his boss. This character was originated by Kenny Baker whom Day replaced. Singer Larry Stevens replaced Dennis Day from November 5, 1944 to March 10, 1946, while the latter served in the Navy.

What can you tell me about Jack's characters?

Expose is an American Latin freestyle vocal group. Primarily consisting of lead vocalists Jeanette Jurado, Ann Curless, and Gioia Bruno, the group achieved much of their success between 1984 and 1993, becoming the first group to have four top ten hits on the Billboard Hot 100 chart from its debut album, including the 1988 #1 hit "Seasons Change". In March 2015, Billboard magazine named the group the eighth most-successful girl group of all-time. The group was popular in dance clubs, mainstream Top 40 and adult contemporary charts in the United States.
During the recording of the group's first studio album Exposure, the personnel of the group changed. Reports vary based on the source. According to People magazine, one of the original singers quit while two of the girls were fired midway through the recording of the first album, but according to Billboard, all three were fired. Arista records felt that the three original singers lacked star potential. Martinee states that he made the decision himself to replace the three girls, while Miller maintains it was all their choice, and Jurado confirms that Lorenzo wanted to leave. Shortly thereafter, Casanas pursued a solo career and Lorenzo pursued other ambitions; they were replaced by Jeanette Jurado and Gioia Bruno. Miller began a solo career; she was replaced by Ann Curless. Lorenzo returned to the dance charts with the Vendetta Records releases "I Wanna Know" in 1988, and "Stop Me if I Fall in Love" in 1990, while Laurie Miller released the 12" single "Parallels" on Atlantic Records and a second single "Love is a Natural Magical Thing" on Meet Me In Miami Records. Laurie evolved into a headline performer frequently showcasing her talents on cruises with a more intimate jazz style, and formed her own entertainment company called Xica productions. Casanas later resurfaced as a solo artist (Sandee) and released a solo album, Only Time Will Tell, which garnered the club hits "You're The One", "Love Desire", and the Clivilles & Cole-produced bassline-heavy hit "Notice Me". She continued to tour actively in dance clubs and freestyle shows, until her death on December 15, 2008, of a seizure at the age of 46. All three original members: Casanas, Lorenzo and Miller later contributed vocals on songs on the Miami group Will to Power's eponymous 1988 debut album. Gioia Bruno also provided lead vocals on Will to Power's 2004 album, Spirit Warrior.

Did Lorenzo have any other good songs?
Lorenzo returned to the dance charts with the Vendetta Records releases "I Wanna Know" in 1988, and "Stop Me if I Fall in Love" in 1990,
