Mark Kennedy (born 20 August 1951) is an Australian musician who has been the drummer for several artists including Spectrum (1969–70), Doug Parkinson in Focus (1971), Leo de Castro (1971–73), Ayers Rock (1973–76), Marcia Hines (1976–83), Men at Work (1985), Renée Geyer (1985–86, 1995–96) and Jimmy Barnes (2005).

"[6] Rudd remembered meeting Kennedy and Putt for the first time "Bill, of course being enormously tall, and Mark actually being a tiny little fella – he must’ve been around 5'3" or 4" or something... there was an astonishing kinda disparity between the two.

[8][10] Due to legal disputes Parkinson found difficulties in recording at that time, although they released a single, "Purple Curtains" (September 1971).

[13] The initial line-up included MacKenzie, Tim Martin on saxophone and flute, and Charlie Tumahai on vocals and percussion (Healing Force, Chain).

[17] Kimball preferred the B-side, "Freedom Train", which he opined was a "driving, prog-jazz" track that "became their signature tune", it was "one of the best Australian progressive recordings of the '70s.

[16] Friends appeared at the Sunbury Pop Festival in January 1973 as a six-piece – Kennedy, de Castro, Green, Martin, McGuire and Oliver.

[14][19] That group's lead single was a cover version of "Lady Montego", which also appeared on their debut album, Big Red Rock (November 1974).

[14][19] Also late in 1974 Ayers Rock members, including Kennedy on drums and percussion, were session musicians for solo singer-songwriter, Jim Keays, debut album, The Boy from the Stars.

[21] At the January 1975 Sunbury Pop Festival, Keays performed most of the album live, with three Ayers Rock members (Brown, McGuire and Kennedy) joining the ensemble to record, "Nothing Much Left" and "Urantia".

[10][11] Southern Star Band issued an album, I'll Be Around, in February 1979 which provided "slick, funky jazz over an R&B foundation" and four singles.

[31] Only the title track, a cover version of The Spinners' song, reached the Kent Music Report's top 40 – peaking at No.

[28] In October 1981 Kennedy provided drums and percussion for Toivo Pilt's (ex-Sebastian Hardie, Windchase) score of a documentary film, Spirit of the Maya.

[38] In October 1987 Kennedy rejoined Leo de Castro & Friends for a two-night series of performances, which was issued later that year on cassette as Voodoo Soul – Live at The Basement.

[41][42] Also in 1993 Kennedy worked with various artists on the soundtrack for Seven Deadly Sins, an ABC-TV mini-series; vocalists were Geyer, Vika Bull, Deborah Conway and Paul Kelly.

[38] Geyer used Kennedy and Berton again on her solo album, Sweet Life (March 1999), with Harry Brus on bass guitar, and Paul Gray on keyboards.

[44] In June that year Kennedy, Berton, Brus and Gray backed Geyer on four tracks for ABC-TV series, Studio 22; they were joined by Dan Knight on organ.
