The famous 'Air On A G String' is synonymous for 'more mature' TV viewers with Hamlet cigars. A long-running series of classic ads used the music as a theme, and when tobacco advertising was banned on television, they ran the entire series as a tribute - power of association in action. I don't think the tune has been used since - it's probably been spoiled for any other campaigns, but if anyone does know if it's been used, post here.
