The song seemed to be called "Money in My Clothes"---it was used on a commercial some years back.
It sounds like a black singing group from perhaps the late '20's or 30's.

Visit here. It may be what you are looking for only I recall it as 'money in my pocket' commercial and the singer was a new comer who made it big with this one.
