Van Halen is an American hard rock band formed in Pasadena, California, in 1972. From 1974 until 1985, the band consisted of guitarist Eddie Van Halen, vocalist David Lee Roth, drummer Alex Van Halen, and bassist Michael Anthony. The band went on to become major stars, and by the early 1980s they were one of the most successful rock acts of the time. 1984 was their most successful album.
David Lee Roth called Eddie to discuss what tracks would be included on a planned Van Halen compilation (work on which had actually begun before Hagar's departure). They got along well, and Eddie invited him up to his house/studio. Shortly afterwards, Roth re-entered the studio with the band and producer Glen Ballard. Two songs from those sessions were added to the band's Greatest Hits album and released as singles to promote it. In September, Van Halen was asked to present an award at the 1996 MTV Video Music Awards. They agreed, and on September 4, 1996, the four original members of Van Halen made their first public appearance together in over eleven years. This helped to bring the compilation to No. 1 on the U.S. album charts. However, unknown to Roth, Eddie and Alex were still auditioning other singers, including Mitch Malloy. The band's appearance on the 1996 MTV Video Music Awards fueled reunion speculation. But several weeks after the awards show, it was discovered that Roth was out of Van Halen again. Roth released a statement in which he apologized to the media and the fans, stating that he was an unwitting participant in a publicity stunt by Van Halen and manager Ray Danniels. The next day, Eddie and Alex released their own statement, claiming they had been completely honest with Roth and had never suggested he was guaranteed to be the next lead singer. Eddie Van Halen would later explain (in regard to the MTV Video Music Awards appearance) that he had initially been embarrassed by Roth's antics while on camera behind Beck, who was giving an acceptance speech for the award that Van Halen had presented to him. Immediately following this, the band had been taken to a backstage press conference where press queries about a reunion tour were met with Eddie Van Halen saying that he needed a hip replacement and would have to record an entire new studio album before any tour. In private Roth told Eddie to avoid talking about negative things like his hip and the two almost came to blows, thereby shattering any chance of a full-scale reunion.

Did they release any songs during the time they were reunited?

Eddie and Alex released their own statement, claiming they had been completely honest with Roth and had never suggested he was guaranteed to be the next lead singer.

John William Carson (October 23, 1925 - January 23, 2005) was an American television host, comedian, writer, and producer. He is best known as the host of The Tonight Show Starring Johnny Carson (1962-1992). Carson received six Emmy Awards, the Television Academy's 1980 Governor's Award, and a 1985 Peabody Award. He was inducted into the Television Academy Hall of Fame in 1987.
On May 1, 1972, the show was moved from Thirty Rockefeller Plaza, New York, to Burbank, California, because of the studio's proximity to the celebrities. Carson often joked about "beautiful downtown Burbank" and referred to "beautiful downtown Bakersfield", which prompted Bakersfield Mayor Mary K. Shell to chide Carson and invite him to her city to see improvements made during the early 1980s. From July 1971, Carson stopped hosting five shows per week. Instead, Mondays featured a guest host, leaving Carson to host the other four weeknights. Shows were videotaped in Burbank at 5:30 pm, fed from there to the Central and Eastern time zone stations via cross-country television line at 8:30 pm Pacific time (11:30 pm Eastern time), and later sent from Burbank to the Pacific time zone stations at 11:30 pm Pacific time. Since only two feeds originated from Burbank, Central time zone stations received the Eastern feed one hour earlier at 10:30 pm local time, and Mountain time stations received the Pacific time zone feed one hour later at 12:30 am local time. In 1980, at Carson's request, the show cut its 90-minute format to 60 minutes on September 16; Tom Snyder's Tomorrow added a half-hour to fill the vacant time. Joan Rivers became the "permanent" guest host from September 1983 until 1986. The Tonight Show returned to using rotating guest hosts, including comic George Carlin. Jay Leno then became the exclusive guest host in fall 1987. Leno joked that although other guest hosts had upped their fees, he had kept his low, assuring himself more bookings. Eventually, Monday night was for Leno, Tuesday for The Best of Carson--rebroadcasts usually dating from a year earlier, but occasionally from the 1970s. Although Carson's work schedule became more attenuated, Tonight remained so successful that his compensation from NBC continued to rise; by the mid-1970s, he had become the highest-paid personality on television, earning about $4 million a year ($15,008,000 today), not including nightclub appearances and his other businesses. He refused many offers to appear in films, including title roles in The Thomas Crown Affair and Gene Wilder's role in Blazing Saddles. He also declined director Martin Scorsese's offer to co-star with Robert De Niro in the 1983 film The King of Comedy, the role of a TV talk-show host then going to Jerry Lewis. In recognition of his 25th anniversary on The Tonight Show, Carson received a personal Peabody Award, the board saying he had "become an American institution, a household word, [and] the most widely quoted American." They also said they "felt the time had come to recognize the contributions that Johnny has made to television, to humor, and to America."
