Definitely Maybe Tour was a world concert tour by English band Oasis in support of their hugely successful debut album "Definitely Maybe".
 The tour, which spanned the UK, Europe, Japan, the US and Canada, included 143 shows over a period of several months in 1994 and 1995 amidst 10 different tour legs.
 The tour started on 6 February 1994 with a short concert at Gleneagles, Scotland, and ended on 22 April 1995 at the Sheffield Arena, which featured an acoustic debut of the future hit Don't Look Back in Anger and was also the last concert to feature original drummer Tony McCarroll.
"Shakermaker" is a song by the English rock band Oasis, written by lead guitarist Noel Gallagher.
 The song was first released as a single on 13 June 1994 and later released on Oasis' debut album "Definitely Maybe".
 The single narrowly missed the UK top 10, peaking at number eleven.
 It was also the first song performed by the band on "Top of the Pops".
 It is the only single from the band's debut album not to be certified Silver by the BPI.
Untitled Film Stills is a series of sixty-nine black and white photographs by American visual artist Cindy Sherman from 1977-1980, which gained her international recognition.
 The artist poses in various stereotypical female roles inspired by 1950's and 60's Hollywood, Film noir, B movies, and European art-house films.
 They represent clichés or feminine types (the office girl, bombshell, girl on the run, housewife, and so on) "that are deeply embedded in the cultural imagination."
 The character in all of these photographs are always looking away from the camera and outside of the frame.
 Sherman casts herself in each of these roles, becoming both the artist and subject in the work.The art historian Rosalind Krauss described this series as “copies without originals”.
 All of the images are untitled, as Sherman wanted to preserve their ambiguity.
 The numbers affiliated with individual works of art are assigned by her gallery, mainly as a cataloguing system.
 In December 1995, The Museum of Modern Art (MOMA) acquired all sixty-nine black-and-white photographs in the series.
 In past exhibitions at MOMA, the photographs are neither hung chronologically, nor grouped according to theme, locale, or content.
 Modest in scale compared to Sherman’s later cibachrome photographs, they are all 8 1/2 by 11 inches, each displayed in identical, simple black frames.
 The glossy finish and scale are meant to reference publicity or promotion stills for a movie.
 In the essay "The Making of Untitled," Cindy Sherman reflects on her beginnings with this series:"I suppose unconsciously, or semiconsciously at best, I was wrestling with some sort of turmoil of my own about understanding women.
 The characters weren't dummies; they weren't just airhead actresses.
 They were women struggling with something but I didn't know what.
 The clothes make them seem a certain way, but then you look at their expression, however slight it may be, and wonder if maybe "they" are not what the clothes are communicating.
 I wasn't working with a raised "awareness," but I definitely felt that the characters are questioning something-perhaps being forced into a certain role.
 At the same time, those roles are in film: the women aren't being lifelike, they're acting.
 There are so many levels of artifice.
 I like that whole jumble of ambiguity.

Liane Balaban (born June 24, 1980) is a Canadian actress.

 She has guest-starred on the television series "", "Covert Affairs" and "Alphas", and joined the cast of "Supernatural" for its eighth season.
"Rock 'n' Roll Star" is a song by English rock band Oasis.
 It is the opening track from their record breaking debut album, "Definitely Maybe".
 Like the majority of the band's songs from this era, it was written by lead guitarist Noel Gallagher.
 Noel said that "Rock 'n' Roll Star" was one of only three songs in which he wanted to say something: "I've pretty much summed up everything I wanted to say in "Rock 'n' Roll Star", "Live Forever" and "Cigarettes & Alcohol", after that I'm repeating myself, but in a different way".
 It became a fan favourite and was often played to close the band's gigs.
Isla Lang Fisher ( ; born 3 February 1976) is an Australian actress.
 Born to Scottish parents in Oman, she moved to Australia at age 6.
 She appeared on the children's adventure series "Bay Cove" and the short-lived soap opera "Paradise Beach", before playing Shannon Reed on the soap opera "Home and Away".
 She has since been known for her comedic roles in "Scooby-Doo" (2002), "I Heart Huckabees" (2004), "Wedding Crashers" (2005), "Hot Rod" (2007), "Definitely, Maybe" (2008), "Confessions of a Shopaholic" (2009), "Rango" (2011), "Bachelorette" (2012), "Rise of the Guardians" (2012), and "Arrested Development" (2013).
Be Here Now is the third studio album by English rock band Oasis, released on 21 August 1997 by Creation Records.
 Oasis had achieved worldwide success with their 1994 debut album "Definitely Maybe" and 1995 follow up "(What's the Story) Morning Glory?
".
 The third album was highly anticipated by both fans and music critics.
 Oasis' management company, Ignition, were aware of the dangers of overexposure, and before release sought to control the media's access to the album.
 The campaign included limiting pre-release radio airplay and forcing journalists to sign gag orders.
 The tactics resulted in the alienation of both the press and many industry personnel connected with the band, and fueled large-scale speculation and wide publicity within the British music scene.
