There's an inside joke at the places I work. People can tell how much I dislike the job by how early in the evening I play the theme from Mash...you know, "Suicide is Painless".
I play it very early...usually first on an outside (read hot) job.

That's probably not an ideal choice for a barbeque for senior citizens.

Oh well...My second suggestion... Sly Stone's "Hot Fun in the Summertime" is nearly
as inappropriate.

That's all I got, folks!
