Question:
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 had been a minor vaudeville performer before becoming a national figure with The Jack Benny Program, a weekly radio show that ran from 1932 to 1948 on NBC and from 1949 to 1955 on CBS. It was among the most highly rated programs during its run.  Benny's long radio career began on April 6, 1932, when the NBC Commercial Program Department auditioned him for the N.W. Ayer agency and their client, Canada Dry, after which Bertha Brainard, head of the division, said, "We think Mr. Benny is excellent for radio and, while the audition was unassisted as far as orchestra was concerned, we believe he would make a great bet for an air program." Recalling the experience in 1956, Benny said Ed Sullivan had invited him to guest on his program (1932), and "the agency for Canada Dry ginger ale heard me and offered me a job."  With Canada Dry ginger ale as a sponsor, Benny came to radio on The Canada Dry Program, on May 2, 1932, on the NBC Blue Network and continuing for six months until October 26, moving to CBS on October 30. With Ted Weems leading the band, Benny stayed on CBS until January 26, 1933.  Arriving at NBC on March 17, Benny did The Chevrolet Program until April 1, 1934. He continued with sponsor General Tire through the end of the season. In October, 1934, General Foods, the makers of Jell-O and Grape-Nuts, became the sponsor strongly identified with Benny for 10 years. American Tobacco's Lucky Strike was his longest-lasting radio sponsor, from October 1944 through to the end of his original radio series.  The show switched networks to CBS on January 2, 1949, as part of CBS president William S. Paley's notorious "raid" of NBC talent in 1948-49. It stayed there for the remainder of its radio run, ending on May 22, 1955. CBS aired repeat episodes from 1956 to 1958 as The Best of Benny.

Answer the question at the end by quoting:

Curved Air are a pioneering English progressive rock group formed in 1970 by musicians from mixed artistic backgrounds, including classical, folk, and electronic sound. The resulting sound of the band was a mixture of progressive rock, folk rock, and fusion with classical elements. Along with High Tide and East of Eden, Curved Air were one of the first rock bands after It's a Beautiful Day and the United States of America to feature a violin. Curved Air released eight studio albums, the first three of which broke the UK Top 20, and had a hit single with "Back Street Luv" (1971) which reached number 4 in the UK Singles Chart.
However, Darryl Way and Sonja Kristina remained interested in working together, and so Way brought in two more "Car Thieves", guitarist Mick Jacques and drummer Stewart Copeland. Though more members of this new lineup came from Stark Naked and the Car Thieves than Curved Air (Kristina being the only member not from the former band), they decided to adopt the Curved Air name for the same reasons that the Kristina/Wedgwood-led band had. With Darryl Way at the helm, this new band often employed the same classical and folk influences as the original band (and even played some of the original band's songs at their shows), but their core sound was rooted in pop, rhythm and blues, and hard rock. Miles Copeland III, still serving as Curved Air's manager, put the group on his own label, BTM.  The band kicked off with a European tour, which started poorly. Way, a notorious perfectionist, grew impatient with the struggling of his bandmates, especially novice drummer Copeland. Then, for reasons no one could pinpoint, the musicians suddenly "clicked" with each other and the band caught fire, quickly becoming a popular and acclaimed live act.  Their studio efforts were another story, however. Phil Kohn left and the band, unable to replace him in time for the sessions for Midnight Wire, relied on guest musicians to play both bass (John G Perry) and keyboards (Peter Wood). Norma Tager, a friend of Kristina's, penned the lyrics to the "Midnight Wire" songs. Kohn was later replaced by Tony Reeves, formerly of Colosseum and Greenslade, but the recording sessions for both Midnight Wire and 1976's Airborne were expensive and highly stressful for everyone involved. Both albums - as well as "Desiree", a single drawn from Airborne - failed to break the charts.  Citing dissatisfaction with BTM Records' inability to support Curved Air financially, Way departed. Though Alex Richman from the Butts Band stepped in on keyboards, the loss of the band's de facto leader was a blow. This line-up's last-ditch attempt at a hit single, a cover version of "Baby Please Don't Go", was another flop. After months of gradually losing steam, Curved Air broke up so quietly that, by Sonja Kristina's recollections, most of the music press wrote off the band's absence as a "sabbatical". Copeland formed The Police, Reeves returned to work as a producer and played in semi-pro band Big Chief along with Jacques, and Kristina and Way both pursued solo careers. Kristina and Copeland maintained the close personal relationship they'd formed while bandmates and were married in 1982.

What did they do when they were unable to replace him?
