The Five Ks (Punjabi: ਪੰਜ ਕਕਾਰ Pañj Kakār) are five Articles of Faith that Khalsa Sikhs wear at all times at the command of the tenth Sikh Guru, Guru Gobind Singh who so ordered at the Vaisakhi Amrit Sanskar in 1699. The Five Ks are not just symbols but Articles of Faith that collectively form the external identity and the Khalsa devotee's commitment to the Sikh rehni "Sikh way of life".

A Sikh who has taken Amrit, dons all five Ks is known as Khalsa ("pure") or Amritdhari ("Amrit Sanskar participant"), while a Sikh who has not taken Amrit but follows all rules and keeps all five Ks is called a sahajdhari ("slow adopter"). One who is neither following rules nor keeping all five Ks can not be called a Sikh.

ਕੱਛ, ਕੜਾ, ਕਿਰਪਾਨ, ਕੰਘਾ, ਕੇਸਕੀ, ਇਹ ਪੰਜ ਕਕਾਰ ਰਹਿਤ ਧਰੇ ਸਿਖ ਸੋਇ ॥

Kachera, Kara, Kirpan, Kanga and Kesh. A person who wears all these Five Kakaars should be considered a Sikh.^{[citation needed]}

ਜੋ ਪਗ ਨੂੰ ਬਾਸੀ ਰਖੇ ਸੋ ਤਨਖਾਹੀਆ। ਇਸ ਲਈ ਹਰ ਗੁਰੂ ਕੇ ਸਿੱਖ ਲਈ ਲਾਜ਼ਮੀ ਹੈ ਕ ਉਹ ਰੋਜ਼ ਦਸਤਾਰ ਸਜਾਵੇ।

One who does not tie a fresh turban is liable for penalty. For this reason it is mandatory for every Sikh of the Guru to tie a turban every day.

Brian Johnson (born 5 October 1947) is an English singer and lyricist who has been the lead singer for the rock band AC/DC since 1980. He was inducted into the Rock and Roll Hall of Fame in 2003, along with the other members of the band.

In 1972, Johnson became one of the founding members of the glam rock band Geordie. After a few hit singles, including UK Top 10 "All Because of You" (1973), the band split up in 1978 then to be reformed by Johnson in 1980. But after signing a new record deal, Johnson was asked to audition for AC/DC, whose charismatic frontman, Bon Scott, had died on 19 February 1980. A fan in Cleveland sent a tape of Johnson performing with Geordie to the band's manager Peter Mensch. Mensch recommended him to the band.

AC/DC lead guitarist and co-founder Angus Young later recalled, "I remember Bon playing me Little Richard, and then telling me the story of when he saw Brian singing." He says about that night, "There's this guy up there screaming at the top of his lungs and then the next thing you know he hits the deck. He's on the floor, rolling around and screaming. I thought it was great, and then to top it off—you couldn't get a better encore—they came in and wheeled the guy off!'" Johnson was diagnosed with appendicitis later that night, which was the cause of his writhing around on stage. The band agreed immediately that Johnson's performing style fit AC/DC's music. Johnson's first album with AC/DC, Back in Black, became the third best-selling album of all time.
