From the BBC:

Unsigned band set to crash charts

Part 1:

‘Koopa, from Colchester, have been together for seven years in var­ious forms and have built up a fan­base on the internet and on the live circuit.’

Part 2:

‘Until 1 January, an artist needed to release sin­gles on CD or another phys­ical format — and there­fore have a record deal — to qualify for the chart.’

Part 3:

‘Their download-​​only single Blag, Steal & Borrow is on course to enter Sunday’s top 40, early sales fig­ures suggest.’

Part 4:

’Record labels have already con­tacted them on the strength of this week’s chart showing.

“It’s absolutely out of this world and fin­gers crossed it could be the start of a good career for us,” Murphy said.

“If someone comes along and gives us an offer, we’ll talk to them.“‘

Part 5:

“But it depends whether we need it. If we can get enough expo­sure and get in the top 40 by the end of the week, do we nec­es­sarily need a large label?

“Probably nowa­days, no you don’t. We’ll get the expo­sure our­selves just from being in the charts.”

Part 6?
