Yep, where I grew up it was Sunday Nights. Wrapup the weekend sports. Tennis had some good themes too. ABC played this for tennis many times as a theme. It was during disco but it worked for me. And the CBS had that classic voice for intros...I think his name was John Robertson......he would go........”Live from the Boca Rotund tennis complex.....CBS sports presents the Lipton Tennis Finals”...and this song would play in the background:

Actually it was CBS for tennis not ABC.
