Of these tracks, only "A Tribute to Buddy Holly" was released as a single in February 1965. While that initially failed to chart, their increasing popularity was fueled by their March 23, 1965 appearance on "Drop-In" which quickly made "A Tribute to Buddy Holly" climb the charts. This prompted Gerhard and his record label Olga Records to quickly issue "Summertime Blues" "Farmer John" and "Cadillac" as singles in late March 1965. While "Farmer John", "Cadillac" and "A Tribute to Buddy Holly" peaked at number 1, 2 and 4 at the same time on "Tio I Topp", "Summertime Blues" missed the charts all together. This was most likely due to the fact that guitarist Janne Frisk provided lead vocals on the track, as opposed to Svenne Hedlund singing it. "Summertime Blues" and "A Tribute to Buddy Holly" became the Hep Stars only singles to feature Frisk on lead vocals.
