tuba-four

A contrabass-brass quartet dat serenades you and thus helps you feel less bored/fatigued while you're wheezingly putting up da light-duty framing-timbers for a new building.

DANG it all with this "tuba-four job" dat I naively volunteered for--- here I thought I was gonna get a live band to play smooth-jazz music for me while I installed da framework for dis here woodshed, but all I ended up with was a nice big pile of 8-foot economy-stud beams!!
