"That Was Then, This Is Now" is a song written by Vance Brescia for his band the Mosquitos and recorded as the title track of their 1985 EP.

[3] Clive Davis of Arista Records heard it and picked it to be the Monkees' comeback single and theme of their 20th Anniversary Tour in 1986.

“That Was Then, This Is Now” became the band's new single and a video for it was filmed at the Arena at Great Adventure in Jackson, New Jersey on July 25.

The video received heavy airplay on MTV, making the song a Billboard Top 20 hit the summer of 1986.

Despite the highly publicized reunion of three original members of the Monkees and their successful 20th Anniversary Tour in that year, it was the band's last US Top 20 hit.
