Hailed in the press as "One of the most versatile and musical drummers in music today", Paul Wertico was born January 5, 1953 in Chicago. He gained worldwide recognition as a member of the Pat Metheny Group from 1983 to 2001. During his tenure with Metheny, Wertico played on ten recordings and four videos, appeared on numerous television shows, and frequently toured around the world. He also won seven Grammy Awards (for "Best Jazz Fusion Performance," "Best Contemporary Jazz Performance," and "Best Rock Instrumental Performance"), magazine polls, and received several gold records.

In recent years, Wertico has continued to tour and perform around the world, as well as around the Chicago metropolitan area, where he is based. This led to the creation of his own band (the Paul Wertico Trio) and collaborations with jazz notables such as Larry Coryell, Kurt Elling, and Jeff Berlin. These collaborations enabled Wertico to be featured on group recordings in a variety of musical genres, and also gave him an opportunity to produce records. In 2009, Wertico's trio joined forces with Marbin, which consisted of Israeli musicians Danny Markovitch (saxophone) and Dani Rabin (guitar). The group performed as Paul Wertico's Mid-East/Mid-West Alliance, and recorded an album for the Chicago Sessions label that received accolades from publications such as the Chicago Tribune, DRUM!, and Modern Drummer. Wertico's current group is Wertico Cain & Gray, featuring multi-instrumentalists David Cain and Larry Gray. A 2013 recording by Wertico Cain & Gray, entitled Sound Portraits, won "Best Live Performance Album" in the 13th Annual Independent Music Awards (2014).

When not touring, Wertico divides his career doing session work, producing, composing, and leading his own groups, as well as teaching. Among the musicians with whom he has played are Eddie Harris, Lee Konitz, Dave Liebman, Sam Rivers, Bob Mintzer, Terry Gibbs, Buddy DeFranco, Roscoe Mitchell, Evan Parker, Jay McShann, Herbie Mann, Randy Brecker, Jerry Goodman, Ramsey Lewis, David Bowie, Charlie Haden, George Coleman, Diane Schuur, Nelson Riddle, Sonny Fortune, Ken Nordine, Tierney Sutton, and many others. Wertico is a member of the Larry Coryell Power Trio. From 2000 to 2007, he was a member of the platinum-record-winning Polish progressive rock band, SBB. He is also the inventor of TUBZ, made by Pro-Mark (who also makes the “Paul Wertico Signature Drum Stick”), as well as a new independently manufactured signature product called “Paul Wertico’s Acousticx”.

John Anthony Helliwell (born 15 February 1945) is an English musician and the saxophonist and occasional keyboardist, woodwind player, and background vocalist for the rock band Supertramp. He also served as an MC during the band's concerts, talking and making jokes to the audience between songs.
Helliwell played with The Alan Bown Set, replacing Dave Green when he joined in January 1966, before joining Supertramp in 1973 along with bassist Dougie Thomson, who convinced Helliwell to make the move. In 2004, Helliwell formed the band Crème Anglaise with Mark Hart, who had joined Supertramp in 1985. This group recorded their eponymous debut album in 2005.
In 1987 Helliwell played on Pink Floyd's album A Momentary Lapse of Reason; his name was misspelled as "Halliwell". This was after Pink Floyd guitarist David Gilmour had played on Supertramp's album Brother Where You Bound. Helliwell also played on French singer Jean-Jacques Goldman's 1985 album Positif, and clarinet on Sara Hickman's 1990 album Shortstop.
During a professional lull in the 1990s, Helliwell began studying for a music degree at the Royal Northern College of Music in Manchester, but he discontinued his studies to join Supertramp on tour when Some Things Never Change was released. In 2004 he contributed saxophone work on the Simon Apple album River to the Sea.
Helliwell contributed clarinet to The Pineapple Thief's song "Fend For Yourself" from their Your Wilderness album which was released in 2016.
Helliwell fronts the Super Big Tramp Band, which has a jazz big band line-up of trumpets, trombones, saxophones and rhythm section. It plays versions of Supertramp tunes, arranged by members of the band, with no vocals, but with Helliwell as the chief soloist. The band first played in Manchester in June 2013. In 2019 the band played at the Manchester Jazz Festival in May and was scheduled to play in Hull and Hamburg later in the year.
In October 2020, Helliwell released Ever Open Door, a CD album of ballads with Helliwell on saxophone and clarinet, with a string quartet and Hammond organ.
