How Long Has This Been Going On is the twenty-fourth studio album by Northern Irish singer-songwriter Van Morrison, "with Georgie Fame and Friends", released in December 1995 in the UK.

According to Van Morrison, "the album took four or five hours to record and Ronnie Scott's was chosen for the vibe.

"[2] Georgie Fame recalled that the album came about after he and Morrison had discussed it for several years when, "I got the band together, and we ran through some ideas one quiet afternoon...that went very well, so Van said, 'Let's do it.

'"[3] Pee Wee Ellis played saxophone and also served as arranger, along with Fame, Morrison and saxophonist Leo Green.

The Daily Telegraph said, "Van huffs and puffs where he should whisper," while Rolling Stone stated, "It's an old blues trick – laughing in the face of trouble – but Morrison does it with such contagious enthusiasm, it sounds fresh again."
