Dublin Bus are celebrating 30 years of service today.
After three decades in operation, Dublin Bus carried an estimated 125.3 million passengers last year - making it by far the busiest public transport provider in the country.
The company has launched a special book to mark its anniversary, filled with stories from drivers throughout the years.
Des O'Toole - who joined the company in 1975, before it became a separate subsidiary of the wider CIE group in 1987 - today remembered one of his fondest memories of the job.
He recalled: "[When] Queen came to Slane, and we did the Slane bus. There were so many passengers, and I had a big ghetto blaster.
"I put a Queen tape on it, and put it down by the microphone. They sang all the way back - there wasn't a word out of them, just singing all the way."
He also explained the story of one customer in particular - Ethel from Bray:
