Melbourne R. "Bob" Cranshaw (born December 10, 1932, in Evanston, Illinois) is an American jazz bassist. His career spans the heyday of Blue Note Records to his recent involvement with the Musicians Union. He is perhaps best known for his long association with Sonny Rollins. Cranshaw has been in Rollins's working band on and off for almost five decades, starting with the 1962 album The Bridge.

Some of his best-known performances include Lee Morgan's The Sidewinder and Grant Green's Idle Moments. Cranshaw also served as the sole session bassist to Sesame Street and The Electric Company songwriter and composer Joe Raposo, and played bass guitar on all songs, tracks, buttons and cues recorded by the Children's Television Workshop during Raposo's tenure.

Although he lacks the name recognition of other bassists, Cranshaw has performed and recorded with a wide range of leading jazz artists, including Ella Fitzgerald, Dexter Gordon, Grant Green, Coleman Hawkins, Jimmy Heath, Joe Henderson, Johnny Hodges, Freddie Hubbard, Bobby Hutcherson, J. J. Johnson, Jackie McLean, Hank Mobley, Thelonious Monk, James Moody, Lee Morgan, Wes Montgomery, Oscar Peterson, Buddy Rich, George Shearing, Wayne Shorter, Horace Silver, Shirley Scott, Stanley Turrentine, McCoy Tyner, Sonny Rollins, George Benson, and Joe Williams.

Theodore Walter "Sonny" Rollins (born September 7, 1930 in New York City) is an American jazz tenor saxophonist. Rollins is widely recognized as one of the most important and influential jazz musicians. A number of his compositions, including "St. Thomas", "Oleo", "Doxy", and "Airegin", have become jazz standards.

Although Rollins was born in New York City, his parents were born in the United States Virgin Islands. Rollins received his first saxophone at age 13. He attended Benjamin Franklin High School in East Harlem. He said that a concert by Frank Sinatra there, accompanied by a plea for racial harmony, changed his life.

Rollins started as a pianist, changed to alto saxophone, and finally switched to tenor in 1946. During his high-school years, he played in a band with other future jazz legends Jackie McLean, Kenny Drew and Art Taylor. He was first recorded in 1949 with Babs Gonzales ( J. J. Johnson was the arranger of the group). In his recordings through 1954, he played with performers such as Miles Davis, Charlie Parker and Thelonious Monk.

Willis Robert "Billy" Drummond, Jr. (b. Newport News, Virginia, June 19, 1959) is an American jazz drummer.

He played in bands from age eight and studied at Shenandoah Conservatory. He moved to New York at the behest of Al Foster in 1986 and shortly thereafter joined the Blue Note band, Out of the Blue (OTB) with whom he recorded their last CD. He subsequently joined the Horace Silver sextet, with whom he toured extensively. He is currently a long-time member of Carla Bley's Lost Chords Quartet. He has played and recorded with Nat Adderley, Ralph Moore (1989 and subsequently), Buster Williams (1990–93), Charles Tolliver (1991), Lew Tabackin and Toshiko Akiyoshi, Hank Jones (1991), James Moody (early 1990s), Sonny Rollins (1994–95), Andy LaVerne (1994), Lee Konitz (1995), Dave Stryker (1996), George Colligan (1997), Ted Rosenthal, Bruce Barth, Andrew Hill (from 1997–2000), Larry Willis (2006 to the present), Toots Thielmans, and Freddie Hubbard (mid-1990s).
