Perry Como was an American singer, radio and television performer whose career covered more than fifty years.
 He is probably best known for his television shows and specials over a period of almost thirty years.
 Como came to television in 1948 when his radio show was selected by NBC for experimental television broadcasts.
 His television programs were seen in more than a dozen countries, making Como a familiar presence outside of the United States and Canada.
"Catch a Falling Star", written by Paul Vance and Lee Pockriss, is a song made famous by Perry Como's hit version, recorded and released in late 1957.
 It was Como's last #1 hit, reaching #1 on the "Billboard" "Most Played by Jockeys" chart but not in the overall top 100, where it reached #2.
 It was the first single to receive a gold record certification, on March 14, 1958.
 The song also topped the Australian charts in 1958.
 The single won Como the 1959 Grammy Award for Best Vocal Performance, Male.
 Its melody is based on a theme from Brahms' "Academic Festival Overture".
 The Como version features the Ray Charles Singers, who sing the refrain as a repeated round.
After Perry Como left the Ted Weems Orchestra in late 1942, he returned to his home in Canonsburg, Pennsylvania with the idea of going back to his barbering profession.
 Como had many offers before and after he was back in his home town.
 As he was preparing to sign a lease to re-open a barber shop, he received a telephone call from Tommy Rockwell, who was with General Artists Corporation.
 Rockwell, who also represented Ted Weems, offered Como a sustaining (non-sponsored) radio program on CBS and also to get him a recording contract.
 The offers made by Rockwell meant remaining in New York to perform with no more road tours as had been the case for many years when Como was with both Freddie Carlone and Ted Weems.
 On the advice of his wife, Roselle, Como agreed to go to New York as it meant he could continue working in the music business and not be separated from his family.
"I Think I Love You" is a song composed by songwriter Tony Romeo in 1970.
 It was released as the debut single by The Partridge Family pop group, featuring David Cassidy on lead vocals and Shirley Jones on background vocals.
 The Partridge Family version was a number-one hit on the "Billboard" Hot 100 in November 1970.
 The alternative rock band Voice of the Beehive scored a hit cover version of their own in 1991.
 There have also been many other cover versions of this song, most notably, Perry Como, Kaci, Katie Cassidy, Paul Westerberg, Constantine Maroulis, and the new "In Search of the Partridge Family" cast on VH1.
Pierino Ronald "Perry" Como (May 18, 1912 – May 12, 2001) was an American singer and television personality.
 During a career spanning more than half a century, he recorded exclusively for RCA Victor for 44 years after signing with the label in 1943.
 "Mr. C.", as he was nicknamed, sold millions of records for RCA and pioneered a musical variety television show.
 Como was seen weekly on television from 1948 to 1963, then continued hosting the "Kraft Music Hall" variety program monthly until 1967.
 His television shows and seasonal specials were broadcast throughout the world.
 Also a popular recording artist, Perry Como released numerous hit records from the 1940s through the 1970s.
 Como's appeal spanned generations and he was universally respected for both his professional standards and the conduct in his personal life.
The Kraft Suspense Theatre is an American television anthology series that was produced and broadcast from 1963 to 1965 on NBC.
 Sponsored by Kraft Foods, it was seen three weeks out of every four and was pre-empted for Perry Como's "Kraft Music Hall" specials once monthly.
 Como's production company, Roncom Films, also produced "Kraft Suspense Theatre."
 (The company name, "Roncom Films" stood for "RONnie COMo," Perry's son, who was in his early twenties when this series premiered).
 Writer, editor, critic and radio playwright Anthony Boucher served as consultant on the series.
"Moments to Remember" is a 1955 popular song recorded by Canadian quartet The Four Lads.
 The song was originally written by Robert Allen and Al Stillman for Perry Como but was turned down by Como's management.
 The Four Lads recorded it in June 1955 for Columbia Records as the B side to the single "Dream On, My Love."
 Bernie Toorish of the Four Lads credited the enthusiastic endorsement of Cleveland radio DJ Bill Randle for increasing radio airtime play and popularizing the recording.
 It eventually reached number 2 on Billboard magazine's top 100 hit list, sold 4 million copies and became the group's first gold record.
Jules Leonard "Buddy" Kaye (January 3, 1918 New York City - November 21, 2002 Rancho Mirage, California) was an American award-winning songwriter, musician, producer, author and publisher.
 His songs were recorded by top performers, including Frank Sinatra, Bob Dylan,Sarah Vaughan, Dinah Washington, Ella Fitzgerald, Perry Como, Elvis Presley, Cliff Richard and Dusty Springfield.
 He scored number 1 hits on the Billboard charts in 1945 with "Till The End Of Time", recorded by Perry Como, and in 1949 with "'A' You're Adorable (The Alphabet Song)", recorded by Como and the Fontaine Sisters.
 Among his most recognizable tunes in pop culture is the co-written theme song to the television series "I Dream of Jeannie".
 In 1975, he won a Grammy Award for best children's album for his production of "The Little Prince," read by Richard Burton.
This is the final album of Perry Como's long career.
 Recorded live at the Point Theatre in Dublin, Ireland, before an audience of 4,500, including Irish President Mary Robinson, it was also recorded on videotape and aired on PBS.
 The videotaped version of the concert shows a man who appears frail and unwell.
 Como struggled to perform and lost his voice at one point during the concert.
 The finished version of the concert is less than 90 minutes long; the recording took more than four hours to complete.
 Despite it all, Como managed to complete his last recorded performance with dignity and professionalism, earning him the applause of his audience.
"And I Love You So" is a popular song written by folk singer and guitarist Don McLean and released on his 1970 debut album, "Tapestry".
 The song has been recorded by many artists in the years since McLean's original version, and it was a 1973 hit for singer Perry Como on his RCA Victor album of the same name, "And I Love You So".
