Per an earlier discussion in this string, I found more information you might find interesting in the WABC tribute site. It's on the opening page:

The funny thing is Wolfman's show sucked despite the enormous promotional dollars spent as described in the article. BTW, it was a real tombstone, not a prop. Still, I often wonder if it was yet another contributing factor seeing George Michael come to WABC. Over the years, I heard WNBC wasn't happy with their Wolfman decision but as we all know now, it created an opening and one Bruce Morrow filled.
Bruce had a good number of lucrative advertisers who sponsored his show. One of the biggest was one mentioned earlier as well - Coco Cola. Bruce did live spots for them and others. So, between the ever growing FM challenges and AM in the fray then as well, I often wonder what was at stake. Anyone know approximately what WABC Radio billed in 1973-1974? As mentioned earlier, the stakes were high. George looked like he would be up to the task.
Here's another example of just how unpredictable radio can be both now and in the past. I don't believe Wolfman's show was live and it sounded like it. If someone could verify - great. Despite all that, in 1973 I don't think anyone would have believed Bruce would be off WABC the following year and George Michael would be the new voice after 13 years.
