The group is best known for their hit recording of "Snoopy vs. the Red Baron", which was first released in 1966 as a 45rpm record single (it reached No. 2 in the US and No. 8 in the UK). The song, "Snoopy's Christmas", is still one of the Top 10 ‘non-traditional’ Christmas songs played during the month of December each year per BMI and ASCAP. Both songs appear on Snoopy and His Friends.
