John Stanley Wojtowicz (March 9, 1945January 2, 2006) was an American bank robber whose story inspired the 1975 film "Dog Day Afternoon".
McVicar is the soundtrack to the film "McVicar" and the fourth solo studio album by Roger Daltrey, the lead vocalist for The Who.
 The film, a biopic of the English bank robber John McVicar, was produced by Daltrey and also featured him in the starring role as John McVicar himself.
 Because all of the then-members of The Who played on the album, it is often considered to be an unrecognized Who album although there was no participation by the band in the songwriting.
