Talking of 'My Old Man's A Dustman'; it came out in (I think, without actually checking) 1960 and was right in the middle of the changeover
from 78 rpm to 45 rpm records, as evidenced by the fact that my eldest brother and his friend both bought the record on the same day,
my brother on 45 and his friend on 78.
They came to our house to play the records for the first time on our Dansette Junior record player.
It's strange to remember nowadays how the purchase of just one record was such an occasion back then.
Both records were vinyl and identical in every way except for size.
So Lonnie must have been among the very last performers to have his records issued in the old format.
