Question: Brian Kay played a voice in which Paul McCartney and the Frog Chorus song?
Context: Paul McCartney: Music & Animation is an animated anthology film compiling three animated short films produced by Paul McCartney.  It was released by Miramax Films on DVD.  The film includes "Rupert & the Frog Song", "Tuesday" and "Tropic Island Hum".  Paul McCartney wrote or composed music for each short. Matters was a Canadian indie rock band from Guelph, Ontario.  The band consisted of Tim Bruton (guitar/synth), Kyle Donnelly (bass), John O'Regan (lead vocals/guitar/keyboard) and Greg Santilly (drums).  They played rock music that had elements of punk, dance, and art rock, and used multiple transitions and hooks rather than traditional verse/chorus song structures. "Girlfriend" is a song written by Paul McCartney.  McCartney thought of the song as one that Michael Jackson might like to record, and mentioned this to Jackson at a party in Hollywood.  Jackson had stated in interviews with the music press in the 1970s that he was a fan of The Beatles and the chance to record a McCartney original helped to inspire his next project.  However, McCartney ended up recording it himself with his band Wings, and it was issued in 1978 on the album "London Town".  Subsequently, it was suggested by Quincy Jones as a possible track for Jackson to record for his 1979 album "Off the Wall".  Jones was unaware that the song had been written for Jackson in the first place.  Jackson's recording omitted the middle eight heard in McCartney's version.  It was issued exclusively in the UK in 1980, as the fifth and final single from the "Off the Wall" album.  This proved to be another hit single for Jackson and one of his first recordings of a Paul McCartney song. "All For Me Grog" is a traditional folk song that was originally popular with sailors and later adopted by folk music performers and pub singers.  It tells the tale of a man who sells all his possessions, and even his wife, to pay for drink and tobacco.  Although the song is effectively about a man's ruin through drink, it is upbeat and celebratory rather than regretful.  It is usually performed as a raucous chorus song.  Grog originally referred to a daily ration of rum that used to be given to sailors in the Royal Navy.  It later came to refer to all types of drink.

He was also the voice of Papageno in the film "Amadeus" and the lowest frog in the Paul McCartney song "We All Stand Together" (The Frog's Chorus). Rupert and the Frog Song is a 1984 animated film based on the comic strip character Rupert Bear, written and produced by Paul McCartney and directed by Geoff Dunbar.  The making of "Rupert and the Frog Song" began in 1981 and ended in 1983.  The film was released theatrically as an accompaniment to McCartney's feature film "Give My Regards to Broad Street".  The song "We All Stand Together" from the film's soundtrack reached No. 3 when released in the UK Singles Chart.  It was released in 2004 as one of the segments of "".

"When Jones' Ale was New" (Roud 139) is an English folk song about men of various trades drinking at an ale-house or tavern.  Other titles include "Joan's Ale is New" and "When Johnson's Ale Was New".

The Driving World Tour was Paul McCartney's first concert tour of the 21st century and of any kind since 1993's New World Tour.  For the first time in nearly a decade, McCartney returned to the road following the death of first wife, Linda McCartney, the death of George Harrison, and 9/11.
