The kids of New Directions perform Fleetwood Mac's 'Don't Stop' on 'Glee' as part of this week's episode featuring the band's classic 'Rumours' album.

The 'Glee' cover is jazzed up with a brass section, a smart move considering that a by-the-numbers remake would've paled in comparison to the original.

The singers take turns on the verses and join together for the optimistic, forward-looking chorus, "Don't stop thinking about tomorrow / Don't stop, it'll soon be here / It'll be better than before / Yesterday's gone, yesterday's gone."

'Don't Stop' reached No. 3 in 1977 and has only become more popular over the years, becoming the de facto theme song for President Clinton throughout the '90s.

The 'Glee' episode featuring 'Don't Stop' and other Fleetwood Mac hits like 'Go Your Own Way' and 'Dreams' airs on FOX tomorrow, May 3.

Rating: 8/10
