back-up channel

There are usually "back-up channels" in which to people use in times when all other channels are on adverts. This saves people from being bored and changing activity to going outside or reading.

Dude - "I'm so glad we have this back-up channel.. i mean police camera action is pretty boring but i'm glad we're not watching some shitty adverts.
Dude-et - "yeah the adverts these days are just all for freakin injury lawyers.."

Back-up Singer

A back up singer is just that, someone who is in the behind hte rest of the band providing additional vocals for the lead vocalist. Back up singers are genrally not the main players in the band thus the term "back up" singers. Not considered to be one of the key players. When and if the back up singers desides not to attend, the concert can techniqually go on without them. This being said, as a back up singer you should know your place and have full understanding that it is the experience that you will use in the future that is trully your reward. Many great singers started off as unpaid back up singers. Genrally getting only food and housing pervided for them. At most a nation wide touring band gives no more then 5% of the pay to Back up's. Not including sales percentages of merchandise. The two most important parts of a back up singers is the ability to hold a note, and the responsibility of bringing your own microphone. If you are unable to do so watch out behind you cause someone else will.
