Air Mail was an alias for several German Rock and Pop Bands on low budget label Europa. They had to produce so-called "vocal productions" for the benefit of Mr. Miller for some bucks. These tracks were spread onto various LP editions with popular topics. The rock music aficionado didn't buy these poor non-originals.
Ordinary European holidaymakers liked this silly summer-hit "Borriquito" from Spain. They also loved that dumb chart hit "Mamy Blue". As they had no more money left after summer holiday in Teneriffa or Rimini, they grabbed this cheap one. Later they noticed: oh no, this is not the same recording as we used to dance to in Mallorca. It's a bluff package. As consequence, these neglected LPs soon vent into secondhand shops, where they stayed for many decades.Nobody liked them.
Most of the songs on these "cheapo" LPs were early exercises done by German "beat" bands or "Krautrock" groups. The funny thing: these early recordings show their versatility.
Air mail is a mixture of tracks by "Petards", "Asterix", Carsten Bohn alias Bert Brac, "Lucifer's Friend", "German Bonds" et al.
So let's skip 3 needless tracks and listen to a pretty "Lucifer's Friend" ballad "All night long" A6, sung by John Lawton. John Lawton also contributes vocals to "Carry me Back" B3. Listen to "Twelve months and a day" B6 by "Asterix" (pre-"Lucifer's Friend"). "Lady Ann" B5 is typical early "Lucifer's Friend"-style as presented on their first 1970 album. Remember the tragedy: John Lawton had to earn his bread for many years as a member of those silly "Les Humphries singers", who produced the preferred popular music for the common German listener. Horror!
