I've posted this song search on many other boards. The songstress must have been a "One Hit Country Wonder or Less" because I've been looking for the song/artist for 25+ years. I heard this song when I lived in Yuma, AZ after being discharged from the Army in October 1974. The song was playing on a local country radio station during the fall of 1974 and the winter/spring of 1975. It was by a female singer and struck a "chord" with me because it was about a rodeo cowboy, something I did in high school and college. Here are the lyrics and the meter was in 3/4 time:
Your collar is frayed and your Levis are dusty, my kinfolks all say you look mean.

Your pickup is old and your trailer is rusty, but your riggin' is ready and clean.

Chorus/Refrain:

I tell you don't ask me for entrance fee money, that ol' rodeo's got my last dime

But I know that you know I'm yours for the askin', cause you love me when you've got time

This song may have been a regional "hit" song because I can't find it on internet searches or in my copy of Joel Whitburn's "Top Country Singles" 1944-1993 by Billboard or in his "Bubbling Under" book. The song was out at the same time as Jeannie Seely's hit "He Can Be Mine"

Thanks,
