On a side note, the phone system has a reserved number range (555-XXXX) for fictitious numbers for TV/movies/etc. to use. This song didn't use that but instead used a real number. When the song came out in 1981, people who had this number got so many phone calls they had to change their number. I'm not sure, but phone companies may have retired the number because it has become impractical to use.
Similar to a social security number[1] that was publicly distributed with wallets at a large retailer in the late 1930s which became the most commonly reused / misused social security number. It also caused the owner lots of grief.
