On the Trail

This song was played at the opening of the Phineas and Ferb episode "The Magnificent Few". The same tune is used for In the Mall, which is sung later in the same episode.

Lyrics
On the trail

Always riding and a roping

On the trail

Where them doggies are a-loping

On the trail

(On the trail)

Nothing worse than bees a-stinging

'Cept this cowboy song we're singing

On the trail

(On the trail)

Sunset's looking awful groovy

On the trail

(On the trail)

'Cause they colorized this movie

On the trail

(On the trail)

On the trail

(On the trail)

On the trail

(On the trail)
