's first hit both in the UK and internationally after the BBC music programme Top of the Pops invited the duo onto the show as a last-minute replacement for another act which had pulled out, as the show's then-executive producer Michael Hurll had seen them on another programme, Saturday Superstore.

[3] Michael wrote the song about a teenage boy's worry that his best friend is getting too committed to a girl when he should be enjoying his youth and the single life.

It features a middle eight aside in which the girl conversely tries to get her boyfriend to ditch the best friend, prompting a vocal battle, akin to a tug of war, between the girlfriend and the best friend, which prompted the 'go for it' aspect of the song, as featured in the title.

The original recording does not feature the voices of Lee or Holliman but that of American backing singer Lynda Hayes.

[3] Their appearance on Top of the Pops broke the record wide open and on the following Monday the distribution centre received some thirty thousand orders,[3] sending the record to number 24 before it eventually peaked at number 3 in November 1982.
