A look into the BBC’s music archives to examine the all-time classic tracks that seem to have been around forever, and get everywhere - apart from the UK Top 40. It’s a journey that sees us heading back in time to the Summer of ‘69 with Bryan Adams and takes in Bowie’s Changes, Dolly’s 9 to 5 and Johnny Cash’s Ring of Fire – just some of the most surprising favourites to feature in this selection of the biggest, most enduring tracks ever written that mysteriously failed to have an impact on the charts the first time around. With crowd-pleasers that still get everyone on their feet and anthems everyone can sing along to, these songs are forever part of the soundtrack to people's lives but always leave them wondering 'why was this not a hit?'
